If it's true that the player is a resident of the United States, since the Casino Guru complaint says they are, it's the second TOS violation of OP. Almost all online casinos with Curacao licenses don't allow US citizens to play. I checked the TOS of Shuffle and their terms state the same thing. Together with the VPN usage, there is now perhaps two rule violations. My gut feeling is telling me that it's not looking good for the OP.
