I know someone that signed up for an account with them, they froze it immediately for suspicious activity. He does nothing with that IP address, reads, social media, that's it. No way to get off the shit list without giving up personal information like a phone number and or alternate email and no guarentee that would fix it.

Their IP was on a blacklist from some shady company for some strange reason. But other companies let you write the company and plead your case, proton does not.

They further suspended a bunch of accounts based on some half baked unproven accusations by the government(s) if I recall.

They aren't trustworthy, they will give you up at the first sign of friction it appears.
