Actually there is talk about the Travelling Circus, that is why it has its own thread. Its people disagreeing with it being problem (or as big a problem as it is) and giving reasons (on why we have to have some games move) isn't the same as you aren't allowed to talk about it.
Admin hasn't banned anyone that I know of lately for going off topic, they are just asking people to stay on topic in threads so they stay relevant for others to read. There is always another thread or you are welcome to make your own if you want to discuss something in another place.
Side Note: I'm not speaking from an admin or fever elite position as I don't have powers to banned etc on the forums (Just to change thread headings and pin posts is all I can do). Just trying to give you my thoughts on that Hatter.
