The ladder system

mmm
btw bnet is already doing alot of things with the cheaters, if you havent notice they started banning cd keys. they have a detection on bnet and they detect bnet third party programs, third party programs are programs that modify brood war scripts. so basicly they know evry 1 that hack, but its about 80% of battle.net so they dont ban theym all or no one would be on bnet any more, so they banning theym gradually just to scare theym.
