Please don't make accusations without the proper proof to back up what you say. Not only does it cause flamefests and yelling of "nub!", but it's also a horrid way to ruin someone's reputation. Post a demo of what you claim, in first person view, and then people are liable to be more polite. But what you just stated above is probably going to bring on some negative comments toward you.
I have one question, however. This fellow you talk of, is his name "HateClan" or "hateclan"? They are both very different people. In this way, you could bring on people from both sides that support either one of these people, both would be against you. You wouldn't have much to go by other than your word versus their's, which is why the miraculous demo feature was created, for purposes such as these.
