EDIT: Maybe a false alert after all, my thread is now visible to all. Still weird that it stayed "deleted" for hours though.
I believe Reddit is now automatically deleting threads about Lemmy (or containing links to Lemmy instances)? A thread I made on r/Save3rdPartyApps got deleted with no explanation within seconds of me creating it and I don't believe it's the sub's mods who did that.
(However, I can see it while logged in. So it's a kind of shadow-deletion)
Can anyone confirm whether referencing Lemmy and/or an instance gets your thread insta-removed?
Just checked now and you're right. Used PowerDeleteSuite to overwrite and delete my comments and now some of them from about 6 years ago are back. Going to wipe it again now
I think part of it is when you run a comment wiper it can only delete the comments from subs that are not private. I wiped my comments the other day, and a few hundred popped back up as the related subs they were in came back from private mode.
Used modmail and contacted three of them individually too, no answer so far. But I highly doubt it's them since the thread got removed within just a few seconds.
