Does Mobage get the CC number though or does Apple/Google get it? I think the latter.

Regardless of who gets the number, Ran's point is valid. If the site in question is using stolen CC numbers, they are essentially "laundering" the stolen funds via your Mobage account (and your legitimate CC number!), therefore purchasing Mobacoins from them is outright illegal.
