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
That’s a hard question to answer. My position is based on where I live and what legal council I have worked with has said in situations I’ve dealt with. My recommendation is, check with an attorney.
