Let me try:
When you start to play a new computer game, after a while, you find out different tricks (bugs?) which help you to improve your skills. But the number of those tricks (bugs?) becomes bigger the longer you play. In the end, everybody uses those tricks (bugs?), which is unbearable, so that you stop playing. Please stop people to exploit common tricks (bugs?).
Maybe he means hacks such as aimbots, autoblock etc. Or just bugusing? Perhaps exploiting that some classes are not balanced to others?
