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
The stuff listed in OP doesn’t really seem like much concern. “What you put on the internet is there forever!” is completely true, and things like this should only make it more concrete that you can’t rely on your service provider to delete information somebody else already archived.
With that being said, default privacy settings - at least on Kbin - seem pretty bad.
