I suppose that could work...But how well? First of all, like some people have said, there would be lots of noobs claiming to be hidden player mods. Secondly, Jagex would have to make many new player mods for it to work at all. Without enough hidden player mods to control rule breakers more, the whole thing would be a waste of time. Though the current system isn't the best, it still works, and the saying goes "If it's not broken, don't fix it." Still, I agree something should be done, but I don't think your idea would work the best.
