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.

Microsoft defender and Apple Xprotect need to remove crawlerware the same as cryotominers were in 2018, and Linux now needs anti virus because of crawler malware too. If you have legitimate crawler needs, contact and consent with webmasters first and ask them for site dumps legitimately. I'm fed up of cloudflare prompts to constantly verify my browser which doesn't work with niche and legacy browsers so we need to go after crawlers at the source.

The bots represent over 90% of the traffic for many/most sites. Since the "AI" systems theoretically don't store data they are querying it constantly. Forum software seems to be hit hardest since the content doesn't cache well. It has made one site I use frequently completely unusable despite significant resources and cloudflare fronting them. It is a lot like the /. effect, but harder to address.

Perplexity.ai: “AI web crawlers are increasingly "destroying websites" in their aggressive hunt for training data for large language models (LLMs). These AI bots are responsible for a rapidly growing share of global web traffic—Cloudflare reports around 30%, and Fastly estimates about 80% of AI bot traffic comes from AI data fetcher bots.

A good way to solve this would be to use the Google antitrust trial to force the creation of a single crawler for the entire web which puts all of the results in to a single, central repository. Everyone can then use that central repository, while charging the users of the repository enough fees to break even on the costs. The antitrust settlement would require Google to construct this central repository. Once the repository exists, all crawling outside of this centralized crawling would be blocked by coordinated ISP action (ie, go use the central repository).

Consider how this would work for a new AI entrant. They'd pay to join the repository collective and then the repository will ship them an array of disks with exabytes of data to get them started. No need to crawl at all. Over time that exabyte array will be remotely updated with newly crawled content. Once they have the exabytes of data in their data center they can copy it out at very high speeds. A complete snapshot of the entire internet is zettabytes, I don't believe anyone has a complete snapshot.

We've had to cut multiple bots off that weren't following robots.txt recommendations.

As someone who's actively fighting this type of traffic, let me share my perspective.
I have been running a small-ish website with user peaks at around 50 requests per second. Over the last couple of months, my site is getting hit with loads of up to 300 requests per second by these kinds of bots. They're using distributed IPs, and random user agents making it hard to block.
My site has a lot of data and pages to scan, and despite an appropriate robots.txt, these things ignore that and just scan endlessly. My website isn't designed to be for profit, and I do this more or less as a hobby and therefore has trouble handling a nearly 10x increase in traffic. My DNS costs have gone up significantly, with 150 or so million DNS requests being done this month.
The net effect is that my website slows down and gets unresponsive by these scans, and I am looking at spending more money just to manage this excess traffic.
Is it destroying my site? No, not really. But it absolutely increases costs and forces me to spend more money and hours on infrastructure than I would have needed to. These things are hurting smaller communities generating significant cost increases onto those who may have difficulties covering those costs, so calling it bullshit isn't exactly accurate.

I know you're saying it's coming from lots of IP addresses, but I wonder if anyone has looked into geofencing to throttle any requests coming out of major data center cities. Normal users would get full speed access, but anyone in the valley or in Ashburn, VA would experience difficulty scraping.
