Ok so lets do this…
We announce our company is no longer accepting US Players…. Our stock value drops by over sixty percent and the owners of our company lose nearly a billion dollars. In return we dont have to pay out commissions to our US affiliates that probably amount to say maybe a few million dollars each month…

Yeah who ever thought up this plot must be the company darling!
Guys I love a good conspiracy theory as much as the next guy, but believe me the casinos who are doing this are doing so at the advice of their attornies. It will probably mean many will cease to exist. It means hundreds of their own employees will be unemployed and thousands of shareholders will lose hundreds of millions of dollars.
This is not a scam to cut out affiliates. This is a reaction to laws the US government is putting into place. If all they wanted to do was cut out affiliates they could have simply announced “We have made the decision to take our marketing in a new direction and announce the closing of our affiliate marketing division. We are sorry for any inconvenience this may cause”
Thats it and they wouldnt have to get destroyed in the stock market or lose thousands of players who wander off to other properties during the down time.
