Fediverse

I don't know where this myth came from, but you don't have a right to erase your public posts from there internet under GDPR. See, for example, https://law.stackexchange.com/questions/32361/does-a-user-have-the-right-to-request-their-forum-posts-deleted

If anything, you might have such rights under copyright law, if your posts cover the threshold for copyright. In that case, you can ask server admins to delete them, and they will have to comply. But the request has to reach them (if they're defederated, the delete button won't teach them, and you'll have to contact them separately).

Very bad indeed! This is the beginning of the end for lemmy.

Ps for those who don't know, copying a deleted comment makes it appear in your pastbin

Oh no, that's not even the half of it. The admin for your instance has access to literally anything on their server, including passwords afaik. If you want privacy, this ain't it chief.
