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
From what I understand instance 1 has to delete data if requested, but instance 2 has no obligation to unless requested. Just like data remains archived in sites like internet archive or other private archives. Just like it works on reddit or any other site currently.
