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
Oh I wish we had the ability to fully delete our content that we’ve posted or that someone has posted of us. Illegal content is a huge concern with federation. As soon as someone pushes something like that, it gets sent to all the federated instances so they have a copy as well. That is a huge concern for instance owners (and honestly the fediverse as a whole).
I run a kbin instance and I’m a software developer for my day job. I honestly don’t have a great answer for “how do we ensure the data we request be deleted on the fediverse is actually deleted.” My best solution would for us to have several federated master databases that we maintain our federated content with. If there is a big delete flag for some content then the child instances will follow suit.
