I loved it, too. But I doubt the idea with the penalties could work very well. You want high value with low entrance costs. As long as you can sign up anonymously you can't get rid of the jerks.
If your purchase of the game is tied to a Steam account, that should work. You'd have to make a new Steam account to avoid these penalties... probably actually a bigger hassle than it sounds, since which account you're logged in as determines which games you can make a snap-decision to play.
