Terrible idea.
Let's just have a hypothetical situation. Player A plays against Player B.
Player A is an amazing player. Player B is not. Player A wins.
Player B gets butt-hurt about losing because he's a prepubescent idiot. Player B decides to report Player A for offensive language, or whatever.
Terrible, terrible plan.
Let's have more hypotheticals, shall we?
Player A is gay. Player B is homophobic.
Player A is black. Player B is racist.
Player A is athiest. Player B is Christian fundementalist.
Player A uses XBox. Player B uses Playstation.
Player A dislikes COD. Player B is a COD fanboy.
Player A dislikes anime. Player B is an otaku.
Player A is a newb. Player B is impatient.
Player A is spy. Player B is not.
Player A is a furry. Player B is 80% of the internet.
Or; Player B is a troll. Player B is a griefer. Player B is a prick. Player B is jealous.
In other words, this system would be so easily abused by people with differing opinions or skill levels that it would cause Valve to lose tons of costumers cause everyone would have to pay a hundred extra just because they thought differently then Player B.
