Flippa doesn't want 'em.

SEDO might be interested for that.

any other suggestions?

Go Fuck Yourself (www.gfy.com)

Lots of business done there and plenty of people with real money. But you need to have thick skin.

You could try ebay. I've seen adult sites listed on there before, although I'm pretty sure it's against their policy as well.

Thanks to all the members who helped out with suggestions so far. Anyone else?

I am interested in this as well.
