Simple Solution: If a program cross promotes, the original referring affiliate should get the benefit of any cross promotion by the affiliate program.
Example: Engineer signs up a player who has never played at any CR casino. Then Engineer should be the beneficiary from any future cross promotion by the affiliate program since he is the original referrer.
However if Dominique refers the same player to a separate CR casino then she gets credit for this player at this casino.
Finally if the affiliate program cross markets the same player to another casino – the original affiliate, Engineer, should get the credit.
This way the original referrer will get the $$ instead of the affiliate program (which did NOT bring the player)
