We needed 100 posts for this perfect solution, replay/answeryou guys are missing the point - whether or not he was caught using cheats in this instance isnt the issue. The issue is that Voobly still detects the cheat software etc on his computer. So no, maybe he didnt use this game... but maybe he used it in the next one or down the line. If you are still in possession of a cheat or cheat software then you deserve to be banned whether you get caught with it or not. Its all about the intent. If there is no intent to using it.. why keep it. Enjoy your Ban. Good riddance.
Thank you sir
