Proton Mail provided Swiss authorities with payment data for [email protected] — the account linked to Stop Cop City protests in Atlanta. The FBI obtained this information through a Mutual Legal Assistance Treaty request on January 25, 2024, identifying the activist behind the anonymous account through their credit card identifier.



Yeah, not sure how it’d work with return addresses and whatnot. But if the letter itself is intercepted there’s probably more that can be used to trace back to you, unless you only handled the money and paper in a clean room.
Well, the entire procedure requires you to first trust the snail mail chain in the first place, so it’s a different category of trust that “trust a CC provider”. Snail mail used to be sacred, but it’s been known not-to for a long while now. And at the point that you can expect the acabs are willing to inkdust and laser your mail for biological traces, that means you are facing a nation-state adversary with nation-state power, so you should be looking into nation-state level defenses instead.
