General or world chat in every game I've ever played is a mess of idiots being idiots. Cheap idiots are no worse than paying ones.
Really obnoxious non-paying idiots can be booted and banned a lot faster than paying ones. The company has nothing to lose for kicking out freeloaders.
kicking them will get rid of some yes,,but not the very worst of them,,the hackers
EVERY F2P game is infested by them,,as soon as they get banned , they make a new account
the fact, that not even blizzard is immune to these people is a reason for concern
worst scenario: it will be like APB,,i wonder how they get anyone to pay for that
