I got a message from a certain casino introducing "PayPal" as an option. They won't credit the money directly, but will "comp" you the amount you send.
Sounds like they are getting desperate. I wouldn't risk this method!
It's like going to a gun shop to buy a gun, and after the background check, you pay for it with a check and ask that the gun be mailed to your home in an unmarked brown package instead of walking out with it.
