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.
That very well might be the case. All of the comments I had left were from a single sub, though IDK if they went private prior to my data wipe or not. No matter, they're gone now.
