Skunky business with skunky online sources = skunky stuff coming your way.
It's possible that the... whoever... who took your card information has no intention of charging your card. They likely don't know how much they could get out of you. What they probably do know, however, is how much your card information (CVV code and all) is worth on the black market. My guess is that's exactly where your card information went: to every crook willing to pay for it.
I strongly advise you call your bank, explain what you did, cancel the card immediately and learn your lesson.
