Seems like this is laying the groundwork for them to begin offering flash sales. Now they can send you a picture/video of a product and give you a limited amount of time to purchase it at a special price. This won't work without having payment methods on file though, and they won't be able to move worthwhile product without getting a base of cards on file first. That's the only logical business I see evolving from this move.
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.
