Actually, if it were ONLY shops and trading, I'd agree to it. If this were applied to all of the forums; I'd give a resounding no. Say there's a discussion going in the... well general discussion forum, and then someone starts flaming even though others are ACTUALLY discussing something, thread creator goes "oh well, let's close this thread," that would just annoy the piss out of anyone who was actually participating in active conversation. So, yeah, shops and trading is where I'd limit it.
