The Daily Challenge is often the highlight of my mornings. I have no aspiration to be in the top 10, or even top 100, but it could happen, on a good day. Except for the cheaters. As of this moment, 7 of the top 10 clearly cheated. There is little doubt. But nothing is done, this happens day after day. I've reported dozens of such players, but only rarely do I get a message stating that someone has been banned. How overwhelming must the evidence be? Many of these players do not seem to cheat in their duels, so perhaps it's considered a lesser "crime". But it is annoying. Ban these players from the Daily challenge, not Duels or other plays, to discourage such behavior.
