it is a health issue, there was a girl back a couple of years who got busted for having just a site to sell her dirty panties, she was making money to get through college. I know they shut her down and she was arrested, not sure what happened from there.

I also worked for a company "bidnow.com" years ago, that was going to try and they had to follow the laws which was you could not sell used panties.
