Crap, Rubbish, BS, Jobsworth, etc.
What rubbish,
It is NOT illegal as yet for US players to gamble online, it is only illiegal for financial institutions to assist in making deposits, and the rules for enforcing this have not yet been finalised.
To say that top level management cannot be flexible when unexpected circumstances lead them to breach their side of a contract is total BS. When players breach their side, even if it is circumstances beyond their control, casino operators will often throw the proverbial book at them.
If the player has released half the bonus, he should receive half, as the casino did not give fair notice of the change, but closed accounts overnight - itself not necessary as there would be no danger of action had they allowed the rest of the month for US players to pull out of gaming gracefully.
What about other players that casinos currently accept. I don't expect the US to be the only country to bring in a ban, especially as the US situation has shown that it might actually work! We can be assured that if our own countries were to make a similar move (granted, unlikely here in the EU), we also would find ourselves out on a limb, and out of pocket too.
Since it seems OK for the player to continue to play poker, surely the released portion of bonus could be placed as cash in the poker account, and the player can immediately withdraw this, and play poker for the remaining half or simply call it a day.
I also have an account at Mansion, but it is dormant because of recent problems posted here on the forum, and I was waiting for signs that players were at least able to get something meaningful done about it. My main concern was the hoops that Mansion keep putting in place to make life harder than it should be for the player, such as this idea that they have to contact support to tell them that they want their funds "promoted" so that they can withdraw everything after wagering the bonus once, but if they miss this obscure step and just wager once the bonus, they lose the ability to ever withdraw it (I would have walked straight into that one myself had I made my second deposit).
