Bonus Whoring for a Bankroll

Stars gives out atleast $70 (they give out more if you sign up people en mass) for each person signed up who plays 100 FPP worth. I'm shocked you can't find people willing to pay out $50 or more... I just assumed most affiliates would offer atleast half of the amount they make. I (as stated) offer $50 but assumed that would be the industry average.
