It's a scam Whenever they ask for credit card info its a scam. I almost got burned with this too, but luckily I used one of those pre-paid credit cards, so I only lost about $90. Live and learn. Your best bet is to stick to the MP's, or the CL girls that are reviewed here(that's what I do), at least you know they're not going to rip you off.
thanks guys, i didn't even take it far enough to see that they wanted a credit card, that would have put up the red light for me for sure. Thanks guys.
