I've often thought, in League of Legends, that I'd pay $100 for access to a special queue which matched me up with other people who had paid $100 to access it. If you earn an account ban, you can probably find a new credit card, level up again, and pay $100, but it should cut down on casual sociopathy. (Yes, that's classist as heck, but after a bad day of LoL I'm pretty OK with that as long as it means that I can play a relaxing game with people who are capable of meeting the absolute minimal norms of civilized society.)
