IP? MAC? Same

Unique fingerprint? Most likely the same with your “private” stuff.

The goal is only to know if the OP edited it or not. It doesn’t really matter who edited it if it wasn’t the OP. The only important information would be that it wasn’t the OP.

OP can edit comment, sign with a different key and claim his comment was edited by the admins.

So we can’t know who really edited the comment unless in the default boring situation: it was OP and he signed it with the correct key which is the same as him just telling “yeah, it was me” or not saying anything at all since it’s the default.

Can’t the admins just edit it and sign with a new key? Either way there won’t be a way to know for sure who edited the comment, you could know if the original poster did it, but well they can just tell you that.

I had the understanding that they would benefit from selling your data

Huh? How?

Might have to research a bit more before my protonvpn renewal comes.

If I were you, I’d stick with proton regardless if your previous understanding is correct or not.

Of the big boys both nord vpn and proton vpn seem to take those issues seriously though proton vpn looks better overall.

They are in Sweden the country famously viewing legal information exchange a crime more serious than murder and part of the Fourteen Eyes, they are also obliged to store your data for half a year . Like whatever your use case for vpn is Sweden based company is not a good choice.

Don’t think Clamav does scanning of everything you launch, it works on files you request to scan usually for mail or file servers. The result is not that great from my experience though neither are with kaspersky or eset and they actually ask money for that.

Why do you need an antivirus? Do you plan installing viruses? It’s pretty uncommon request for Linux desktop as you’d have to put some effort to finding and running some Linux virus(actually, please dm if you find one).
