There was a guest on NPR yesterday who had a new book out about how Shamu taught her all this stuff, but it was essentially how it's easier to train animals (including people) by rewarding good behavior, rather than punishing bad behavior. So maybe the answer is to reward those with high ratios. A porn BT site I use has a system set up where not only your ratio, but the amount you've uploaded gives you "forum perks" which allow you to do such things as have an avatar or post in certain forums. Oddly, my ratio there is even better than it is here, but I haven't originated anything...
