International tourism to the United States [1]faces an unprecedented 8.2% decline in 2025 , with the World Travel and Tourism Council projecting a $12.5 billion loss in visitor spending -- the only decline among 184 economies analyzed. Canadian visitors, traditionally comprising 28% of international arrivals, have dropped by approximately 25% through July.

Seattle tour operators report 30-50% fewer Canadian customers with many explicitly citing recent tariff policies and political rhetoric as deterrents. The newly implemented $250 "visa integrity fee" for certain countries compounds existing concerns about immigration policies and National Guard deployments in major cities. Tourism Economics now projects full recovery to pre-pandemic levels won't occur until 2029, three years later than initially forecast.

College students have integrated generative AI into their academic routines at an unprecedented scale as [1]85% report usage for coursework in the past year , according to new Inside Higher Ed survey data. The majority employ AI tools for brainstorming ideas, seeking tutoring assistance, and exam preparation rather than wholesale academic outsourcing. Only 25% admitted using AI to complete assignments entirely, while 19% generated full essays.

Students overwhelmingly reject institutional policing approaches, with 53% favoring education on ethical AI use over detection software deployment. Despite widespread adoption, 35% of respondents report no change in their perception of college value, while 23% view their degrees as more valuable in the AI era.

An anonymous reader shares a report:

> Speaking to The Logan Bartlett Show on Friday, Salesforce CEO Marc Benioff said the use of AI agents had enabled him to "rebalance" his headcount in the customer support division [1]by trimming 4,000 jobs . "I've reduced it from 9,000 head to about 5,000 because I need less heads," Benioff said. Benioff called the first eight months of 2025, during which an estimated 10,000 jobs have been lost to AI, "eight of the most exciting months of my career."

>

> "There were more than 100 million leads that we have not called back at Salesforce in the last 26 years because we have not had enough people," Benioff said. "We just couldn't call them back. But we now have an agentic sales that is calling back every person that contacts us."

> The European Union will deploy additional satellites in low Earth orbit to [1]strengthen resilience against GPS interferences and will improve capabilities to detect it, EU Defence Commissioner Andrius Kubilius said on Monday. His remarks followed an incident on Sunday in which the GPS system aboard European Commission President Ursula von der Leyen's aircraft was jammed en route to Bulgaria. Bulgarian authorities suspect the jamming was due to due to interference by Russia, an EU spokesperson said.

The century-old duty-free import exemption that transformed American online shopping [1]has ended , The Atlantic argues, closing a loophole that allowed packages valued under $800 to enter the United States without tariffs. The de minimis threshold, raised from $200 in 2016, processed millions of daily shipments directly from overseas sellers to American consumers.

China lost access earlier this year; the exemption now terminates for all countries. Platforms including Shein, Temu, and marketplace sellers on Amazon, Etsy, and eBay built business models around direct shipping from manufacturing hubs in Asia and elsewhere. Import duties will apply to all international packages regardless of value, with tariffs reaching 50% for some countries. The policy shift affects everything from $30 specialty faucet parts shipped from Britain to handmade crafts from India, fundamentally altering the economics of cross-border e-commerce that emerged over the past decade.

Americans are [1]having a record low amount of sex -- even less than they did during the Covid-19 pandemic -- according to a new study led by researchers at the Institute for Family Studies. WSJ:

> This continues the downward shift in sexual activity that has been worrying sociologists and psychologists for decades. For the report, called " [2]The Sex Recession ," researchers at the IFS analyzed the data on sex and intimacy in the latest General Social Survey produced by NORC at the University of Chicago, which was collected in 2024 and released in May. They found that just 37% of people age 18-64 reported having sex at least once a week, down from 55% in 1990. The decline is even more striking for young adults: Almost a quarter of people age 18-29, or 24%, said they had not had sex in the past year; this is twice as many as in 2010.

>

> Much has been written in recent years about the trend of young people having less sex, attributed to everything from stunted social skills to a rise in internet pornography. Yet the IFS study shows that the same trend holds true for people up to the age of 64, of all sexual orientations, both married and single. (After age 64, there was no significant change in the amount of sex people have, largely because this group reports having sex less frequently to begin with, the researchers said.)

Waymo robotaxis are repeatedly selecting identical parking spots in front of specific Los Angeles and Arizona homes between rides, puzzling residents who [1]document the same vehicles returning to precise locations daily . The company states its vehicles choose parking based on local regulations, existing vehicle distribution, and proximity to high-demand areas but cannot explain the algorithmic specificity.

Carnegie Mellon autonomous vehicle expert Phil Koopman attributes the behavior to machine learning systems optimizing for specific spots without variation. Waymo said it had received neighbor complaints and has designated certain locations as no-parking zones for its fleet. The vehicles comply with three-hour parking limits, according to Los Angeles Department of Transportation regulations, governing commercial passenger vehicles under 22 feet.

A [1]review of published meta-analyses examining protein supplementation found no evidence supporting intake beyond 1.6 grams per kilogram of body weight daily, according to an analysis by cardiologist Eric Topol. The review examined multiple randomized controlled trials encompassing thousands of participants. The most widely cited Morton study, which included 1,863 participants across 49 trials, showed no statistically significant benefit at higher protein levels, with a p-value of 0.079.

Recent research from Washington University identified the essential amino acid leucine as activating mTOR in macrophages, promoting atherosclerosis progression. The mechanism was demonstrated in both mouse models and human studies measuring circulating monocyte changes following acute high-protein challenges increasing dietary protein from 22% to 50% of energy intake. Current USDA data indicates 55% of American men and 35% of women already exceed the 0.8 g/kg/day recommendation from the National Academy of Medicine. The protein supplement industry, exemplified by David bars containing 28 grams of protein in 150 calories using a modified plant fat called EPG, projects $180 million in 2025 sales.

"Typically when something is available to "buy," ownership of that good or access to that service is offered in exchange for money," [1]writes Ars Technica .

"That's not really the case, though, when it comes to digital content."

> Often, streaming services like Amazon Prime Video offer customers the options to "rent" digital content for a few days or to "buy" it. Some might think that picking "buy" means that they can view the content indefinitely. But these purchases are really just long-term licenses to watch the content for as long as the streaming service has the right to distribute it — which could be for years, months, or days after the transaction. A lawsuit [2]recently filed against Prime Video challenges this practice and accuses the streaming service of misleading customers by labeling long-term rentals as purchases. The conclusion of the case could have implications for how streaming services frame digital content...

>

> [The plaintiff's] complaint stands a better chance due to a California law that took effect in January banning the selling of a "digital good to a purchaser with the terms 'buy,' 'purchase,' or any other term which a reasonable person would understand to confer an unrestricted ownership interest in the digital good, or alongside an option for a time-limited rental." There are some instances where the law allows digital content providers to use words like "buy." One example is if, at the time of transaction, the seller receives acknowledgement from the customer that the customer is receiving a license to access the digital content; that they received a complete list of the license's conditions; and that they know that access to the digital content may be "unilaterally revoked...."

>

> The case is likely to hinge on whether or not fine print and lengthy terms of use are appropriate and sufficient communication. [The plaintiff]'s complaint acknowledges that Prime Video shows relevant fine print below its "buy" buttons but says that the notice is "far below the 'buy movie' button, buried at the very bottom" of the page and is not visible until "the very last stage of the transaction," after a user has already clicked "buy."

Amazon is sure to argue that "If plaintiff didn't want to read her contract, including the small print, that's on her," says consumer attorney Danny Karon. But he tells Ars Technica "I like plaintiff's chances. A normal consumer, after whom the California statute at issue is fashioned, would consider 'buy' or 'purchase' to involve a permanent transaction, not a mere rental... If the facts are as plaintiff alleges, Amazon's behavior would likely constitute a breach of contract or statutory fraud."

[1]PC Gamer reports :

> The Diablo team is the next in line to unionize at Blizzard. Over 450 developers across multiple disciplines have voted to form a union under the Communications Workers of America (CWA), and they're now the fourth major Blizzard team to do so... A wave of unions have formed at Blizzard in the last year, including the [2]World of Warcraft , [3]Overwatch , and Story and Franchise Development teams. Elsewhere at Microsoft, [4]Bethesda , ZeniMax Online Studios and [5]ZeniMax QA testers have also unionized...

>

> The CWA says over 3,500 Microsoft workers have now organized to fight for fair compensation, job security, and improved working conditions.

CWA is America's largest communications and media labor union, and [6]in a statement , local 9510 president Jason Justice called the successful vote "part of a much larger story about turning the tide in an industry that has long overlooked its labor. Entertainment workers across film, television, music, and now video games are standing together to have a seat at the table. The strength of our movement comes from that solidarity."

And CWA local 6215 president Ron Swaggerty said "Each new organizing effort adds momentum to the nationwide movement for video game worker power."

"What began as a trickle has turned into an avalanche," [7]writes the gaming news site Aftermath , calling the latest vote "a direct result of the union neutrality deal Microsoft struck with CWA in 2022 when it was facing regulatory scrutiny over its $68.7 billion purchase of Activision Blizzard."

> We've come a long way since small units at Raven and Blizzard Albany [8]fended off Activision Blizzard's pre-acquisition attempts at union busting in 2022 and 2023, and not a moment too soon: Microsoft's [9]penchant for mass layoffs has cut some teams to the bone and left others warily counting down the days until their heads land on the chopping block. This new union, workers hope, will act as a bulwark...

>

> [B]ased on preliminary conversations with prospective members, they can already hazard a few guesses as to what they'll be arm-wrestling management over at the bargaining table: pay equity, AI, crediting, and remote work.

"I have no musical talent at all," says Oliver McCann. "I can't sing, I can't play instruments, and I have no musical background at all!"

But the Associated Press describes 37-year-old McCann as a British " [1]AI music creator " — and last month McCann signed with an independent record label "after one of his tracks racked up 3 million streams, in what's billed as the first time a music label has inked a contract with an AI music creator."

> McCann is an example of how ChatGPT-style [2]AI song generation tools like Suno and Udio have spawned a wave of synthetic music, a movement most notably highlighted by a fictitious group, [3]Velvet Sundown , that went viral even though all its songs, lyrics and album art were created by AI. Experts say generative AI is set to transform the music world. However, there are scant details, so far, on how it's impacting the $29.6 billion global recorded music market, which includes about $20 billion from streaming.

>

> The most reliable figures come from music streaming service Deezer, which estimates that 18% of songs uploaded to its platform every day are purely AI generated, though they only account for a tiny amount of total streams, hinting that few people are actually listening. Other, bigger streaming platforms like Spotify haven't released any figures on AI music... "It's a total boom. It's a tsunami," said Josh Antonuccio, director of Ohio University's School of Media Arts and Studies. The amount of AI generated music "is just going to only exponentially increase" as young people grow up with AI and become more comfortable with it, he said. [Antonuccio says later the cost of making a hit record "just keeps winnowing down from a major studio to a laptop to a bedroom. And now it's like a text prompt — several text prompts." Though there's a lack of legal clarity over copyright issues.]

>

> Generative AI, with its ability to spit out seemingly unique content, has divided the music world, with musicians and industry groups complaining that recorded works are being exploited to train AI models that power song generation tools... Three major record companies, Sony Music Entertainment, Universal Music Group and Warner Records, [4]filed lawsuits last year against Suno and Udio for copyright infringement. In June, the two sides also reportedly entered negotiations that could go beyond settling the lawsuits and set rules for how artists are paid when AI is used to remix their songs.

>

> GEMA, a German royalty collection society, has sued Suno, accusing it of generating music similar to songs like "Mambo No. 5" by Lou Bega and "Forever Young" by Alphaville. More than 1,000 musicians, including Kate Bush, Annie Lennox and Damon Albarn, released a [5]silent album to protest proposed changes to U.K. laws on AI they fear would erode their creative control.

>

> Meanwhile, other artists, such as will.i.am, Timbaland and Imogen Heap, have embraced the technology. Some users say the debate is just a rehash of old arguments about once-new technology that eventually became widely used, such as AutoTune, drum machines and synthesizers.

"Nearly 400 students, many of them entrepreneurs, have so far made the journey to Forest City to study everything from coding to unconventional theories on statehood," [1]reports Bloomberg .

"They're building crypto projects, fine-tuning their physiques and testing whether a shared ideology — rather than just shared territory — can bind a community."

> They have descended on Forest City to attend Network School, the brainchild of former Coinbase Inc. executive and "The Network State" author Balaji Srinivasan. In this troubled megaproject once envisaged to house some 50 times its current population, they're conducting a real-life experiment of sorts with Srinivasan's vision of "startup societies" defined less by historical territory than shared beliefs in technology, cryptocurrency and light regulation... Mornings are spent in product sprints and coding sessions; afternoons in seminars exploring topics from the Meiji Restoration to Singapore's statecraft and the mechanics of decentralized governance. Guest lectures double as both technological deep dives and ideological sermons, according to half a dozen students interviewed by Bloomberg. The campus also mirrors Silicon Valley's infatuation with longevity and health, right down to a commercial-grade gym and specially designed workout routines. Students follow a protein-heavy diet...

>

> After co-founding DNA testing startup Counsyl in 2008 and serving as its chief technology officer, Srinivasan spent five years at venture capital firm Andreessen Horowitz, first as general partner and then as board partner. He joined Coinbase as CTO in 2018 when the crypto exchange bought a portfolio company he oversaw and left after a little over a year, according to his LinkedIn profile. In a 2013 speech at Y Combinator's Startup School, Srinivasan brought his ideas about what he saw as a fundamental conflict between some modern nation-states and innovation to a wider audience. In the address, he advocated for Silicon Valley's "ultimate exit" from the U.S., which he argued was obsolete and hostile to innovators. In essence: If the society you live in is broken, why not just "opt out" and create a new one?

>

> "The Network State: How To Start a New Country," published in 2022, expanded on Srinivasan's "exit" concept to outline how online, ideologically aligned communities can use crypto and digital tools to form new, decentralized states. A network state can be geographically dispersed and bound together by the internet and blockchains, he says, and the aim is to gain diplomatic recognition... On the Moment of Zen podcast in September 2023, he outlined how the "Gray Tribe" — entrepreneurs, innovators and thinkers — can retake control of San Francisco from the Blues using a variety of tactics, like allying with local police. The effort would involve gaining control of territory, according to Srinivasan, who didn't advocate for violence. "Elections are just the cherry on the cake," he said. "Elections are just a reflection of your total control of the streets."

The cost of attending Network School "starts at $1,500 per month, including lodging and food, for those who opt for a shared room."

[1] Futurism reports :

> Earlier this week, buried in the middle of a [2]lengthy blog post addressing ChatGPT's propensity for [3]severe mental health harms , OpenAI admitted that it's scanning users' conversations and [4]reporting to police any interactions that a human reviewer deems sufficiently threatening.

>

> "When we detect users who are planning to harm others, we route their conversations to specialized pipelines where they are reviewed by a small team trained on our usage policies and who are authorized to take action, including banning accounts," it wrote. "If human reviewers determine that a case involves an imminent threat of serious physical harm to others, we may refer it to law enforcement."

>

> The announcement raised immediate questions. Don't human moderators judging tone, for instance, undercut the entire premise of an AI system that its creators say can solve broad, complex problems? How is OpenAI even figuring out users' precise locations in order to provide them to emergency responders? How is it protecting against abuse by [5]so-called swatters , who could pretend to be someone else and then make violent threats to ChatGPT in order to get their targets raided by the cops...? The admission also seems to contradict remarks by OpenAI CEO Sam Altman, who [6]recently called for privacy akin to a "therapist or a lawyer or a doctor" for users talking to ChatGPT.

"Others argued that the AI industry is hastily pushing poorly-understood products to market, using real people as guinea pigs, and adopting increasingly haphazard solutions to real-world problems as they arise..."

Graphic designer Lisa Carstens "spends a good portion of her day working with startups and individual clients looking to fix their botched attempts at AI-generated logos," [1]reports NBC News :

> Such gigs are part of a new category of work spawned by the generative AI boom that threatened to displace creative jobs across the board: Anyone can now write blog posts, produce a graphic or code an app with a few text prompts, but AI-generated content rarely makes for a satisfactory final product on its own... Fixing AI's mistakes is not their ideal line of work, many freelancers say, as it tends to pay less than traditional gigs in their area of expertise. But some say it's what helps pay the bills....

>

> As companies struggle to figure out their approach to AI, recent data provided to NBC News from freelance job platforms Upwork, Freelancer and Fiverr also suggest that demand for various types of creative work surged this year, and that clients are increasingly looking for humans who can work alongside AI technologies without relying on or rejecting them entirely. Data from Upwork found that although AI is already automating lower-skilled and repetitive tasks, the platform is seeing growing demand for more complex work such as content strategy or creative art direction. And over the past six months, Fiverr said it has seen a 250% boost in demand for niche tasks across web design and book illustration, from "watercolor children story book illustration" to "Shopify website design." Similarly, Freelancer saw a surge in demand this year for humans in writing, branding, design and video production, including requests for emotionally engaging content like "heartfelt speeches...."

>

> The low pay from clients who have already cheaped out on AI tools has affected gig workers across industries, including more technical ones like coding. For India-based web and app developer Harsh Kumar, many of his clients say they had already invested much of their budget in "vibe coding" tools that couldn't deliver the results they wanted. But others, he said, are realizing that shelling out for a human developer is worth the headaches saved from trying to get an AI assistant to fix its own "crappy code." Kumar said his clients often bring him vibe-coded websites or apps that resulted in unstable or wholly unusable systems.

"Even outside of any obvious mistakes made by AI tools, some artists say their clients simply want a human touch to distinguish themselves from the growing pool of AI-generated content online..."

The U.S. government site climate.gov offered years' worth of climate-science information — until its production team was [1]fired earlier this summer . The site "is [2]technically still online , but has been intentionally buried by the team of political appointees who now run the National Oceanic and Atmospheric Administration," [3]reports the Guardian .

But now "a team of climate communication experts — including many members of the former climate.gov team — is working to resurrect its content into a new organization with an expanded mission."

> Their effort's new website, [4]climate.us , would not only offer public-facing interpretations of climate science, but could also begin to directly offer climate-related services, such as assisting local governments with mapping increased flooding risk due to climate change. The effort is being led by climate.gov's former managing editor, Rebecca Lindsey, who, although now unemployed, has recruited several of her former colleagues to volunteer their time in an attempt to build climate.us into a thriving non-profit organization... "None of us were ready to let go of climate.gov and the mission...." Lindsey's new team has received a steady flow of outside support, including legal support, and a short-term grant that has helped them develop a vision for what they'd like to do next...

>

> As multiyear veterans of the federal bureaucracy, at times they've been surprised by the possibilities that the new effort might offer. "We're allowed to use TikTok now," said Lindsey. "We're allowed to have a little bit of fun...

>

> The climate.us team is also in the process of soft-launching [5]a crowdsourced fundraising drive that Lindsey hopes they can leverage into more permanent support from a major foundation.... "[W]e do not yet have the sort of large operational funding that we will need if we're going to actually transition climate.gov operations to the non-profit space." In the meantime, Lindsey and her team have found themselves spending the summer knee-deep in the logistics of building a major non-profit from scratch.

"A class of drugs called beta-blockers — used for decades as a first-line treatment after a heart attack — doesn't benefit the vast majority of patients," [1]reports CNN . And in fact beta-blockers "may contribute to a higher risk of hospitalization and death in some women but not in men, according to groundbreaking new research..."

> Women with little heart damage after their heart attacks who were treated with beta-blockers were significantly more likely to have another heart attack or be hospitalized for heart failure — and nearly three times more likely to die — compared with women not given the drug, according to a study [2]published in the European Heart Journal and also scheduled to be presented Saturday at the European Society of Cardiology Congress in Madrid... The findings, however, only applied to women with a left ventricular ejection fraction above 50%, which is considered normal function, the study said. Ejection fraction is a way of measuring how well the left side of the heart is pumping oxygenated blood throughout the body. For anyone with a score below 40% after a heart attack, beta-blockers continue to be the standard of care due to their ability to calm heart arrhythmias that may trigger a second event...

>

> The analysis on women was part of a much larger clinical trial called REBOOT — Treatment with Beta-Blockers after Myocardial Infarction without Reduced Ejection Fraction — which followed 8,505 men and women treated for heart attacks at 109 hospitals in Spain and Italy for nearly four years. Results of the study were [3]published in Mem>The New England Journal of Medicine and also presented at the European Society of Cardiology Congress. None of the patients in the trial had a left ventricular ejection fraction below 40%, a sign of potential heart failure. "We found no benefit in using beta-blockers for men or women with preserved heart function after heart attack despite this being the standard of care for some 40 years," said Fuster, former editor-in-chief of the Journal of the American College of Cardiology and past president of the American Heart Association and the World Health Federation... In fact, most men and women who survive heart attacks today have ejection fractions above 50%, Ibáñez said [Dr. Borja Ibáñez, scientific director for Madrid's National Center for Cardiovascular Investigation]. "Yet at this time, some 80% of patients in the US, Europe and Asia are treated with beta-blockers because medical guidelines still recommend them...."

>

> While the study did not find any need to use beta-blockers for people with a left ventricular ejection fraction above 50% after a heart attack, a separate meta-analysis of 1,885 patients published Saturday in The Lancet did find benefits for those with scores between 40% and 50%, in which the heart may be mildly damaged. "This subgroup did benefit from a routine use of beta-blockers," said Ibáñez, who was also a coauthor on this paper. "We found about a 25% reduction in the primary endpoint, which was a composite of new heart attacks, heart failure and all-cause death."

"AI web crawlers are strip-mining the web in their perpetual hunt for ever more content to feed into their Large Language Model mills," [1]argues Steven J. Vaughan-Nichols at the Register .

And "when AI searchbots, with Meta (52% of AI searchbot traffic), Google (23%), and OpenAI (20%) leading the way, clobber websites with as much as 30 Terabits in a single surge, they're damaging even the largest companies' site performance..."

> How much traffic do they account for? According to Cloudflare, a major content delivery network (CDN) force, [2]30% of global web traffic now comes from bots . Leading the way and growing fast? AI bots... Anyone who runs a website, though, knows there's a huge, honking difference between the old-style crawlers and today's AI crawlers. The new ones are site killers. Fastly warns that they're causing " performance degradation , service disruption, and increased operational costs." Why? Because they're hammering websites with traffic spikes that can reach up to ten or even twenty times normal levels within minutes.

>

> Moreover, AI crawlers are much more aggressive than standard crawlers. As the InMotionhosting web hosting company notes, they also tend to [3]disregard crawl delays or bandwidth-saving guidelines and extract full page text, and sometimes attempt to follow dynamic links or scripts. The result? If you're using a shared server for your website, as many small businesses do, even if your site isn't being shaken down for content, other sites on the same hardware with the same Internet pipe may be getting hit. This means your site's performance drops through the floor even if an AI crawler isn't raiding your website...

>

> AI crawlers don't direct users back to the original sources. They kick our sites around, return nothing, and we're left trying to decide how we're to make a living in the AI-driven web world. Yes, of course, we can try to fend them off with logins, paywalls, CAPTCHA challenges, and sophisticated anti-bot technologies. You know one thing AI is good at? It's getting around those walls. As for robots.txt files, the old-school way of blocking crawlers? Many — most? — AI crawlers simply ignore them... There are efforts afoot to supplement robots.txt with [4]llms.txt files. This is a proposed standard to provide LLM-friendly content that LLMs can access without compromising the site's performance. Not everyone is thrilled with this approach, though, and it may yet come to nothing.

>

> In the meantime, to combat excessive crawling, some infrastructure providers, such as Cloudflare, [5]now offer default bot-blocking services to block AI crawlers and provide mechanisms to deter AI companies from accessing their data.

"According to a new study, wearing the right kind of perfume or cologne can enlarge your brain's gray matter," [1]writes ScienceAlert

> Researchers from Kyoto University and the University of Tsukuba in Japan asked 28 women to wear a specific rose scent oil on their clothing for a month, with another 22 volunteers enlisted as controls who put on plain water instead. Magnetic resonance imaging ( MRI) scans showed boosts in the gray matter volume of the rose scent participants.

>

> While an increase in brain volume doesn't necessarily translate into more thinking power, the findings could have implications for neurodegenerative conditions such as dementia. "This study is the first to show that continuous scent inhalation changes brain structure," [2]write the researchers in their published paper. We've seen scents like this [3]improve memory and [4]cognitive performance , but here the team wanted to try a longer-term experiment to see how triggering our sense of smell might lead to measurable changes in brain structure...

>

> It's difficult to pin down exactly what's causing this boost in gray matter. Another possibility raised by the researchers is that the rose scent is actually labeled as unpleasant by the brain, with the subsequent emotional regulation responsible for the PCC working harder and increasing in size. The researchers hope that the findings could be useful in the development of aromatherapies that boost mental health and brain plasticity...

The Washington Post covers "a [1]string of false reports of active shooters at a dozen U.S. universities this month as students returned to campus."

> The FBI is investigating the incidents, according to a spokesperson who declined to specify the nature of the probe. While universities have proved a popular swatting target, the agency "is seeing an increase in swatting events across the country," the FBI spokesperson said... Local officials are frustrated by the anonymous calls tying up first responders, straining public safety budgets and needlessly traumatizing college students who grew up in an era in which gun violence [2]has in some way shaped their school experience...

>

> The recent string of swattings began Thursday with a false report to the University of Tennessee at Chattanooga, quickly followed by one about Villanova University later that day. Hoaxes at 10 more schools followed... Villanova also received a second threat. As the calls about shootings came in, officials on many of the campuses pushed out emergency notifications directing students and employees to shelter in place, while police investigated what turned out to be false reports. (Iowa State was able to verify the lack of a threat before a campuswide alert was sent, its police chief said. [They had a live video feed from the location the caller claimed to be from.]) In at least three cases, 911 calls reporting a shooting purported to come from campus libraries, where the sound of gunshots could be heard over the phone, officials told The Washington Post...

>

> Although false bomb reports, shooter threats and swatting incidents are not new, bad actors used to be more easily traceable through landline phones. But the era of internet-based services, virtual private networks, and anonymous text and chat tools has made unmasking hoax callers far more challenging... In 2023, a Post investigation found that more than 500 schools across the United States were [3]subject to a coordinated swatting effort that may have had origins abroad...

>

> [In Chattanooga, Tennessee last week] a dispatcher heard gunfire during a call reporting an on-campus shooting. "We grabbed everybody that wasn't already out on the street and got to that location," said University of Tennessee at Chattanooga Police spokesman Brett Fuchs. About 150 officers from several agencies responded. There was no shooter.

[4]The New York Times reports that an online group called "Purgatory" is "suspected of being connected to several of the episodes, including reports of shootings, according to cybersecurity experts, law enforcement agencies and the group members' own posts in a social media chat." (Though the Times, couldn't verify the group's claims.)

> Federal authorities previously connected the same network to a series of bomb scares and bogus shooting reports in early 2024, for which three men pleaded guilty this year... Bragging about its recent activities, Purgatory said that it could arrange more swatting episodes for a fee.

USA Today [5]tries to quantify the reach of swatting :

> Estimated swatting incidents jumped from 400 in 2011 to more than 1,000 in 2019, [6]according to the Anti-Defamation League , which cited a former FBI agent whose expertise is in swatting. From January 2023 to June 2024 alone, [7]more than 800 instances of swatting were recorded at U.S. elementary, middle and high schools, according to the K-12 School Shootings Database, created by a University of Central Florida doctoral student in response to the Parkland High School shooting in 2018.tise is in swatting... David Riedman, a data scientist and creator of the K-12 School Shooting Database, estimates that in 2023, [8]it cost $82,300,000 for police to respond to false threats.
