Threads where are they?

I have noticed a couple of times of late, that when i click on a thread i get a notice up saying this thread does not exist, it happened recently on UA`s blog, these threads were not removed to the Gash Barge, they were removed, why is this and who is the Moderator that decides what can be said and not said? I`m not talking about cases in court etc just a normal blurb. Why are we being censored? :whew:
