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
Part of it will depend on what data you’re holding, and part will depend on who’s running the instance. A lot of people won’t be covered, but I’d wager there’s some here and there who need to consider it.
