This article goes into 5 main categories of hacking/cheating, you can arm yourself with that information so that you can precisely identify the techniques of the cheaters to more effectively provide the proof needed to ban them. One thing I can say hands down that if you are a cheater, the time to do it is now, the authorities will become more involved as people start hunting you down.
Japan has started arresting video game hackers. Well deserved, I applaud the efforts of the authorities and I will vote for any politician/other that seeks to pursue this precise form of using authority.
As I become older as a gamer, I'm becoming more interested in starting a security contracting firm (think Blackwater) that would hunt cheaters and their service providers down, I have military contacts that are avid gamers and perhaps they could be interested (let me know Brad). The idea seems wonderfully appealing especially since we have a republican president who wants to flood the defense department with money.
Who else would enjoy seeing some cheaters go to prison?
