First, If I am a hacker, there's no meaning I write this here. Honestly, I am not a hacker.
Many people, not only a few, called me a hacker when they were caught while creeping. At first, I explained a lot and they still insisted that I'm a map hacker. Now, I just say "whatever".
They didn't know how I sount. Also, if they really were familiar with the game, they would know I was not a hacker afterwhile because sometimes they caught me, too. But still, they would say I pretended to be caught.
Or, is this like a strategy to disturb opponant's mind? Claim he's a hacker and let him be angry so that they get more chance to win? These days many people just start insulting their opponants and the very first second of the game even though they never met you at all. I am wondering if they behave like that all the time besides playing warcraft 3.
At last, it is Ok that they suspect someone hacks sometimes, but please, do some research about the replay after. Or it is just an excuse for their weakness.
