Heads up that deleted posts and threads are no longer shown by default, but there is a new preference setting to make them still show up if you want. When enabled, deleted threads and replies can be seen for up to 3 days (might increase that since you now have power to turn them on or off).
I created the ghost posts a few years ago to give the community some info about who deleted the posts and why, because at the time there were a few people relentlessly using every deleted post to spread FUD and start conspiracy theories about their favorite grievance, and people were believing it too.
So I had to add them, but then I learned that the lingering public display of rejected posts also increases the resentment of the offending poster probably 10 fold, causing even more problems. The deleted post were also pushing live messages down. I think this new move will bring things a bit more into balance.
