I think RB is simply increasing profits. If you really wanted to provide motivation to actively market your casinos you would either:
a) Increase percentage payouts
b) Provide more tools to help affiliates
c) Add more casinos to your program
d) Try to improve player retention/conversion percentages
I’m sure there are many other improvements you could make, and asking your affiliates would give you more ideas than you could handle.
B&D would cost nothing but time. C would eventually help both affiliates and RB.
Decreasing the percentage on the off event that nobody signs up is not very inviting. If nobody new signs up, we not only suffer financial losses of having no new players, but then you go ahead and take an extra 5% off us!
