Federated services have always had privacy issues but I expected Lemmy would have the fewest, but it’s visibly worse for privacy than even Reddit.
- Deleted comments remain on the server but hidden to non-admins, the username remains visible
- Deleted account usernames remain visible too
- Anything remains visible on federated servers!
- When you delete your account, media does not get deleted on any server
So the key thing here is, “are you aware that the data is part of a legal proceeding or crime?”
If no, deleting it as part of normal operations is perfectly legal. There are plenty of VPNs which do not log user information, and will produce for the authorities all of the logs they retain (i.e. an empty log file).
From an ethical standpoint, keeping peoples’ data which they want removed, against their wishes, based on the hypothetical that at some point someone might do something wrong, is by far the less ethical route.
“You might do something bad, so I’m going to keep all your data whether you like it or not!” <- the bad thing
It’s cute how you think I’m going to take legal advice from you. You do you, have a nice evening.
