Although it works for that, I feel like that would be more of a carrot for users so that they can transition to a more reputable business model. They can use that for a short time to get the card data, but then begin selling their own goods etc. I would be surprised if they left it at this considering how young their userbase is. Mixing 'cash for pics' with a userbase predominantly under 18 in a multi-billion dollar business does not sound like a good idea to me.
