I agree manners are a good thing. Unfortunately, abuse pops up at random and very frequently on here, especially when your rating gets high. These days I mute opponents and spectators immediately upon entering a match to save myself the aggravation of enduring foul, childish language as well as OBVIOUS attempts to throw me off with random comments.
To all those who are well mannered good sports, don't take it personally if I don't talk to you.
To all the rest. Well , hehe, you know what you can do with it. I'm just here to have fun.
