If everyone was aware at the start that cheating would wind up having them banned from the majority of servers in NZ, then they would not do it in the first place. More people would play, more quality play, people that might of become cheaters would put in the hard yards and get good instead, less work for admins banning and maintaining the ban list. Some publicity suggestions. Further to this, if the admins have given themselves the right to prevent people playing, they need to take some responsibility for their actions. There must be recourse to get yourself removed from the ban list.
People make mistakes on both sides of the fence.
Some Admin might have something personal against you.
