Sore Losers[closed]SN

I am not going to accuse anyone straight out because i know there are multiple people doing it. What I am getting at is the problem of sore losers or just plain jerks, who leave a crappy rating on someone with out any reason. I am new to this as you can tell I have only a handful of games under my belt. But, I feel i have been unjustly rated by my peers. Just because i won against some one doesn't give them the right to be a a poor sport. I would rather not 'get back' at the person and leave them a bad score because it would just perpetuate itself. Should i just forget it and take it as part of the game or what?
