Wait...matchfixing is way worse then cheating. It is same in regular sports. Lets say cheating si doping. When you dope/cheat, you just giving yourself a chance to win. It is not 100% sure you would win.
When you matchfixing, you have basically 99.99% certainty that the match/race/... end result will be as you expect/want. If there is betting gambling behind the sport, then this is HUGE fraud and many ppl can loose their money.
I understand that Brax was young and stupid and that he is for many here fan favorite, but he is there with other guys like DazeD, AzK and Steel. Valve had to do something and when you see how matchfixing is being handled in other sports, they are lucky that they did not went to prison. Doping is punished with bans for some periods, very rarely lifetime ban, but matchfixing is illegal also outside of rules for any sports. It IS much worse than cheating.
