I like your idea regarding a system of rewards in that it would tend to benefit non-subscribing users and encourage them to abide by the TOU. However, it has been my experience that many of the most offensive posters are those that are paying subscribers who seem to think that because they give IHub $10/month they have the right to post a continuous stream of whatever drivel they can concoct. I do understand that a portion of the camaraderie that develops on a board is born of the "Hi, How are ya"'s and a lot of posters enjoy watching a stock tick by tick, but if you are trying to alter the mix by rewarding non subscribers I think you should also consider a similar structure for penalizing offensive subscribers as well. Just a thought;)
