Actually a lot of the players are now using "nice try team" or "good try team". Which is a way of acknowledging to your team players, that are pointing out the cheats, that all you can do is accept that the Cheaters are a part of the game. So they have a choice, try or chose not to try. But if you chose not to try, then why play. The best way to consider fighting cheaters is to liken it playing a P&P game and your DM is annoyed so throws your party into a random boss fight. At that point all you can do is try.
