Deleted comments remain on the server but hidden to non-admins, the username remains visible
This is a negative behavior by Lemmy, in my opinion. Deleted comments should be purged after some time. Tildes does the same thing - I think with 30 days?
Deleted account usernames remain visible too
These should be replaced with some random string of characters or something like DeleteUser<numberhere> or something.
Anything remains visible on federated servers!
This is just a concession of federation.
When you delete your account, media does not get deleted on any server
Honestly, this is definitely something that can be added - and in fact it might even be beneficial to server costs. Alongside optional deletion of cached data from other instances maybe a year or two after the data arrived.
People need to remember that Lemmy is an alpha software - we haven't even reached the big 1.0 release
can't anyone who runs a lemmy instance script all that in the db?
alternately, can't anyone who claims to do so just not do it in the db? it's not like you would ever know.
