Sadly, yes, but that's because the Disposal board is where all deleted posts and threads go.
This is to prevent the accidental deletion of threads if a spambot posts in them.
From what I've read at the SCS Forums, GalanDun once deleted a thread that he made, without noticing because of trolls posting so many NSFW stuff. When Shane came online, he personally deleted all the troll posts, and moved the thread back.
Can't remember which one though. I think it was on 8 November? Who knows...
