I feel you man, ive been banned from at least 5 clan server in the last 2 weeks for owning with tv missles while solo'ing an attack chopper. I practiced so much in empty servers and with buddies, and now i get banned for my skill because some noobs cant deal with getting killed.... its lame, and unlike stat padding its very hard to prove that they banned you for the wrong reasons. All you can really do is ignore them if they start bitching (bitching back will only get you banned faster...) and hope they just let you keep playing.
