Sounds like a stupid policy.
well it doesnt always work but i usually ban all the friends who correct spelling, grammar, and other dumb crap like that thinking they are superior (generally forum members), and i usually ban people who come in and are like "I hope this server is worth my time." or "Wow, this server is full of stupid people who cannot spell correctly.", "Your argument provides no factual backing to support your claims so therefore I am correct in what I say and." shut the forget up
p.s- any tenticle blocks or ascii terror player avatars get banned as well
--keep your forums crap on the forums no one wants to hear about it in game
