Point resets don't work. The player who gets the point reset may be a very good player; however, he or she is now playing with only 1000 points. So, he or she is going to take away a lot more points in a win and lose a lot less points in a loss than is "deserved." While this system, when suggested, receives praise from many users, the downside of punishing unsuspecting future opponents is often neglected. This alone is enough for this suggestion to be REJECTED
Some, including myself, have mentioned a point "penalty" that attempts to perform more of a corrective than punitive role and should not have these unfair effects on the point system. I'm not optimistic of even that type of punishment going through, but it is out there and I will continue to support it.
If I had to give my best estimation of what type of augmented punishment has the best chances of going through due to the amount of user support, I would pick the stripping of certain medals, as mentioned in this thread: viewtopic.php?f=4&t=170171
