I don't think it's possible to prevent all the cheaters. There have always been some of them, and no matter how hard we try, we find them everywhere. Some examples are at work, in games, or domains like trading. I think we should focus on our work, and once we do everything right, there is no point in worrying. For example, when I started to learn this domain, it seemed like a maze. Once I discovered Dough Roller , little by little, it started to make sense. Now, I don't care about cheaters since I am satisfied with my work.
