Luckily in those deleted threads, no one posted or replied as usually it is unfair for those posters who post good in those threads but later found out that the whole thread is gone along with their posts.
I am not sure what kind of posts and quality content you can generate in threads that discuss ways to become a god or reptilian, or his nonsense tips about immortality and the other types of unnecessary noise he was creating. Anyone discussing such things and relying on those posts to remain on a Bitcoin forum shouldn't be surprised if they notice plenty of post deletions.
