How do we find out the cause of deleted posts not shown in the modlog?
I'm just going through my past history, and looking for anything where the subject is "*Permanently Deleted*" and where the Modlog for that community shows nothing.
"Permanently deleted" normally means the poster has removed their account and content. In this case, your comment hasn't been removed, but the post you were replying to is gone, because the person who made the post deleted their account. It reads permanently deleted, because that's now the post title in the database
it's also the case for deletions without account deletions, but iirc there is some delay before it gets rewritten in the db to allow the user to undelete it for a bit of time.
Deleted means that the creator deleted it, which won't be logged to the modlog.
Removed means a moderator or admin removed it, which will be logged to the modlog.
It could also be that the user was instance/community banned with the purge content option enabled. Which might confuse you, because the posts won't have a modlog entry regarding their removal. The purge content option's status is not logged along with their ban. So be sure to check if they are instance/community banned as well.
What the actual hell. There's nothing in the fedimemes modlog for why it was deleted, and also, the post itself doesn't appear deleted in my history....
