s4s doesn't have janitors, so if you are getting your threads deleted it's being done specifically by a mod himself, same with bans, janitors can't ban, but they can report posts to the mod queue for a mod to act upon it which is i believe how most people get banned, but without janitors this means a mod himself was actually reading the board and came across your post and decided to ban you for whatever reason which is pretty funny when you think about it (also you could get reported by a normal user i guess)
