Nobody purposefully makes this possible.
It happens all the time though and is very easy to do. Bonus abusers and advantage players in casinos do it routinely, and the casinos rarely catch it. And believe me, they would if they could. It involves minor, easy deception.
The situation is creating a very undesireable player culture. As in perfectly honest players are being taught how to cheat and deceive.
I am not hostile towards affiliates who offer rakeback – it’s a very competative industry and it gives you an edge – at least for now. And don’t think it makes you not welcome here – you certainly are.
How the industry adjusts is to be seen in the long run.
