When I suggested something similar in another topic, Refusal to resign (http://www.chess.com/forum/view/community/refusal-to-resign?page=3), writing:
"What about a new feedback system that would allow everyone to leave his comment about the correctenes of players after every game, so that it would be possible to avoid non-reliable contenders?"
someone defined this as a way of "ratting people out".
And you wrote a right thing! But often those who are ratting you out, by action, blame the same on you. There is nothing at all wrong with such feedback. You and I can afford not to think about the notorious politicorrectness
Well, look at my position vs him. What can I say better ?
