So I just got notified that two people who I played against had their accounts closed because of fair play, anyone know why? Is it just because of the rating difference, because I've been matched up against lower rated opponents, or were they abusing the matchmaking? I think that one of the people told me it was their friend's account they were smurfing on, but I'm not sure. Thoughts?
