CR was brilliantly thought out, whether they took this into consideration or not, is anybody's guess but back then things were not as complicated and I think that everything was done with no thought to anything but to retain.
However innocent intention or not, CR has always been in position to cross-promote without tagging ... (hold on Renee, I am not saying they did it to be unethical), but fact remains that every time someone goes into the casino rewards website to claim their loyalty points, they are made aware that there are other casinos in the network, that the loyalty kickbacks are good at any of the 20+ casinos in the network.
Now IMHO it makes sense that people who joined the first casino .... likely did not know about one of the other themes in the network, which the reason they joined that first casino was because it had the CR seal, meaning they pay and are fair.
but when you find out that a casino which has a theme you prefer ... is also in the same safe network ....
see where I am going with that?
CR doesn't need to cross-promote in the sense of the word where this accusation is headed.
