I posted something on lemmy.ml (mine is lemmy.world) and deleted it right away. I thought it was gone, but a few days later I searched my profile on Mastodon and saw the post there, with many comments. Then I checked the community from another profile and my post was threre.
Was this a bug or we can only delete posts from our account server?
If servers are overloaded, federation will never happen, whether posting, editing, or deleting. It’s just not that reliable all the time.
