Banning cheater give negative buzz?

Why banning the cheater give me negative buzz? I understand that player who gets banned go make a negative review. But I think it doesn’t make any sense, why can’t I get half and half? Players should be happy when I ban cheaters.

Another idea on how to approach this is to generate negative buzz whenever a subscriber sees another subscriber cheating (or even a percent chance to create negative buzz). This will give the player a good incentive to stop any cheating players quickly, and will also cue players in on cheating problems early on when negative buzz starts rising unexpectedly.
