wow, this is one big thread and just yesterday it was 3 pages! I see it has now been clarified and i agree with the majority that cross promotion is bad.. very bad for affiliates.
I am 100% certain that as a casino group you would want to introduce new promotions at the different 6 casinos. That is business but at the same time it is stealing our players from one casino to another (if promo is attractive)
Hence, i HOPE no other Microgaming casino i promote follows in that model.
I guess the solution would be to join affiliate programs that have single casinos under their belt and skip the issue all together should more programs follow.
