I have a 2 or 3 free sites out there floating in the ether that have the content from one of those "here today, fuck you tomorrow" sponsors - Pimp Dust (they now claim to be invitation only. the paysites are still around, but my links are dead). When a surfer clicks the ads, they literally get nothing.
