PSA: You can't delete photos uploaded to Lemmy. So don't (accidentally) upload a nude
(tech.michaelaltfield.net)
Are updates authenticated? Or can I send an update to lemmy.world from 123.123.123.123 (which is not the IP address of feddit.de) that you have edited your comment to say "I don't like pizza"?
If updates are not authenticated this really could be a big problem.
