Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

Proton requires an email because they offer a free tier, without some way of regulating users their servers would be overrun with bots and spam...

The difference between what recently happened with Mullvad and what happened in the article you linked about Proton is that with Mullvad they were looking for general user data for VPN usage, not a specific persons email account like with Proton.

If a copyright holder or law enforcement is in a torrent swarm and logs all of the IP addresses of the seeders of Frozen II and then goes looking for the users of those IPs then ProtonVPN and Mullvad VPN would have the same response - No logs, no idea

Sure, not having to register with an email with Mullvad and IVPN is great but they're not offering port forwarding any more so we recommended ProtonVPN and you said you didn't trust them because they followed the law, if Mullvad or IVPN offered email services then they would have to do the same thing Proton did.

If you make a ProtonVPN account with the sole purpose of torrenting then all you have to do is not publicise your Proton email along with the fact that you're torrenting and then nobody can really do anything about that because law enforcement can't go to Proton like they did with that guy because they don't know the account linked to you.

I didn't hear about the onion issues, but again unless Proton was specifically told to log specific users IPs then even if they were redirected, their IPs wouldn't have been logged in those instances.

Its still user error, he must have publicised his Proton account, law enforcement found out about it and his IP was logged under Swiss law, thats user error. Its crappy that thats law but if you're going to do things like that then you should know how to protect yourself properly
