That comment is deleted, did you actually read it? If you check the modlog you will see that I didnt defend CSAM at all, but was only defending another user. Just to make it clear for you, I am against pedophilia. Its honestly impressive, you dont know me at all you try to paint me as some kind of evil supervillain over a few misinterpreted comments.
It seems that the post is getting refetched over federation and marked as deleted again. So you will have to run that SQL query regularly (eg in a cronjob) to restore the post every time. Its also worth setting locked = true to prevent users from commenting.
By the way I opened an issue to fix this properly: https://github.com/LemmyNet/lemmy/issues/6044
You can run the SQL command update post where id = 53505862 set deleted = false. That way it will be visible on db0 again, although not on other instances.
Oh yes, I need to rewatch this one!
