From time to time ppl are kicked from our server with this; [04.28.2006 23:45:30] VIOLATION (GAMEHACK) #80164: I have noted that the punks busted site is removeing players with this violation from their master ban list. When I ask about what it is I get the run around. In short they say its not a hack violation, if not wouldnt PB update their software? So is this a violation we should worry about?
