Looks a fair proposal there Greg, and an overview would be you are simply asking for one new player per Month and no one would be affected? Its a pity you are doing this AFTER affiliates have signed up, but you do have to make a profit and affiliates can as usual vote with their feet, should they find your new terms and conditions not agreeable.
I love the part about you paying the funds from site copiers income to the injured party that is pure class and something which needs addressing, which you are prepared to address.
Just my two cents
