The best way for US affiliate is opening an offshore bank account to receive casino affiliate payment. It is 100% legal. register a cheap foreign company then open a company bank account offshore. Then you may register a foreign company Moneybookers. casino affiliate can not send money to US moneybookers. but casino affiliate can send money to foreign moneybookers. Once your foreign moneybookers receives payment, re-send money to your US moneybookers. Then you withdraw money to your US bank account.
