So I tried to play online blackjack at sportfanatik.com and won 30 bucks from them. I, however, get an email from them saying that they need me to fax them a copy of my driver's license because they are doing a random audit before they can send me out my check. Is this legit? I wondering this because I know they probably have my credit card number on file since that was the only way I could buy their virtual chips. Should I be worried about identity theft in this situation if I do fax them my driver's license since they are located outside the US?
