??? players not getting punished for int feeding

There was someone in one of my games that int fed and trolled in my game. We all reported him and he has not been punished what so ever. I looked at his match history and he continues to play games. I added him and he told me nothing happened. I went on a smurf and int fed and trolled to see if I get punished.. I didn't... lol nice system. It was actually kind of fun int feeding, making other players mad. Maybe ill continue doing so til you fix your shitty game.
