If you notice, those threads in Spamtastic that have an specific topic do not go that much off-topic!
As you can see threads such as 'FFNet Bar', 'Which fruit are joo?', or 'Gossip of FFnet' do not have an specific topic! So there we post whatever it comes to our mind!
But check, for example the thread 'Your funniest quote' in which the people didn't go off-topic at all.
