Great idea, not going to work IRL. The problem is that the only people that use these systems are those that are being targeted against. My first and only game of DOTA2 put me in a group of not-my-language speaking players who promptly tried to destroy my profile. Having this system may make the online experience better for the few that don't get hit with crap, but I think it will only serve to discourage online play by legitimately polite gamers over all. Gamers will definitely be afraid to play, just not the ones Microsoft is trying to scare off.
