With the amount of spamming and trolling I've been seeing, I think people should only be able to post outside of the newbies section if they have a post count of over 9000.
Won't this just increase the spamming and trolling?
No, the current system works so that if a troll wants to troll he has to post 50 Useful Posts. Along with other possible methods.
There isn't a perfect solution to trolls but at least they do something good before they go crazy.
