So let's say someone takes your suggestion to do so they become a better cheater. What the next move in the cat and mouse game to catch the cheat you just designed? To be a good cheater, you should be thinking in these kinds of terms. If you can think of a cheat, but not how to get caught, you'll not be a good cheater. If you can think of a cheat, then realize how it can be caught, then modify the cheat, think of how to beat that, lather/rinse/repeat, you'll probably be a really good cheat. At that point though, I think you could be a better use to society doing something else with that critical thinking. So unless there's a bunch of money involved, it probably won't be attracting the brightest.
