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



This is an interesting thought, as data transfer between the US and EU has been an issue with other social networks. Federation between an EU instance and a US instance could be seen as the same thing - data for EU users is being transferred to non-EU servers.
