Online games are a form of competition. Competition of any sort usually has a physical aspect, and a psychological aspect. If Competitor A can use insults to get Competitor B flustered to the point that it affects Competitor B's ability to play the game, then Competitor A has given himself or herself an advantage. If Competitor A's insults get Competitor B to quit playing altogether, then it's even more of an advantage for Competitor A. Once you realize this, the insults become irrelevant. Just ignore them. It's not difficult, and they really have no impact unless you let them bother you.
