Proton Mail Helped FBI Unmask Anonymous 'Stop Cop City' Protester (404media.co)

(Friday March 06, 2026 @05:00PM (BeauHD) from the follow-the-money dept.)


Longtime Slashdot reader [1]AmiMoJo shares a report from 404 Media:

> Privacy-focused email provider Proton Mail provided Swiss authorities with payment data that the FBI then [2]used to determine who was allegedly behind an anonymous account affiliated with the Stop Cop City movement in Atlanta , according to a court record reviewed by 404 Media. The records provide insight into the sort of data that Proton Mail, which prides itself both on its end-to-end encryption and that it is only governed by Swiss privacy law, can and does provide to third parties. In this case, the Proton Mail account was affiliated with the Defend the Atlanta Forest (DTAF) group and Stop Cop City movement in Atlanta, which authorities were investigating for their connection to arson, vandalism and doxing. Broadly, members were protesting the building of a large police training center next to the Intrenchment Creek Park in Atlanta, and actions also included [3]camping in the forest and lawsuits . Charges against more than 60 people have since been dropped.

Proton mail has never, despite what is being claimed, promised to not store your IP address. A subpeona can compel them to do so, and it has in the past, and this will continue to happen. If your security depends on your IP address not being unmasked, you need to use at least one VPN.

If you self hosted then the subpeona would be delivered to your ISP, which will happily comply- likely quicker than protonmail.

NO EMAIL SERVICE WILL COMMIT A CRIME FOR YOU

If you only connect through VPNs, then the email service will provide the VPN's IP. If the VPN is then contacted and they have no logs, then they will not be able to correlate the IP to a user. This is your only chance at anonymity under these circumstances: some VPN plus some private mail service that never knows your real IP address. Note that proton is a strong choice here because if you previously connected via your real IP they won't have a log of that; they'll only start saving your IP when they get a warrant. There are other equally strong private email choices, but ALL OF THEM WILL DELIVER YOUR IP IF THEY KNOW IT.

Proton mail has strong privacy policy, privacy protection and minimal data retention. But if money changes hands some data is essentially retained as it is legally required. Any data retained is subject to discovery by a court order.

This doesn't in any way minimise Proton Mail's offering or promises. It's worth remembering they are privacy focused, and not a dedicated service to obfuscate you. There's a different.

That's correct, and it's not their mission. When I was looking into Proton mail a few years ago, they were promising privacy against tracking by corporations, not anonymity from government investigation. They were positioning their services as an alternative to Google's & Microsoft's data gathering. There is a free tier, so some people might be able to successfully use it for fully covert communications, but that's not what interested me in it.

Courts grant wide ranging search warrants for much less than that. Especially when you're looking for organizers trying to do those things at scale. This is true for basically all nations within Western jurisprudence (with exception of France, where investigative Magistrate himself may show up at your door, and he and his people won't be nice about it).
