This isn't the first time actually. I remember someone wanted to sell their wife as well.
Personally, if you're at the point where you need to sell yourself over the internet for money, then you have proven that humanity can't be saved. Not only will people sell themselves, but there are people willing to pay for it. In this we can assume people would pay for anything and sell anything, given the need for money. And besides, these girls only sold themselves to get into college. Is it gonna be worth it?
