Privacy-focused email provider Proton Mail provided Swiss authorities with payment data that the FBI then 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 camping in the forest and lawsuits. Charges against more than 60 people have since been dropped.
