According to certain people it is considered "Network Manipulation" which is a ban able offense, well here is my response to that. The funny thing is, "if" what you're saying is true, only the person leaving and causing the cheese would get banned. Nobody else since they don't "exploit" the network only said person doing the "cheese". So even if I do cheese it I won't get banned unless I'm the one leaving and causing said "cheese" and sadly I'm to lazy to quit the game so it looks like I won't get banned :)
