A site I used to surf years ago..
http://www.mrdouble.com
Used to be free, but he's gone pay now. Funnily enough he mentions on his join pages that his CC processor dropped him when he wouldn't remove all his questionable stuff (incest, pedo stories, etc).. And believe me, there's a lot of that shit on there.
I imagine if it was run by a clued webmaster it'd be making a mint, but probably be a big target with that pedo shit on there.
Cheers,
