YPN was giving me BBW dating ads :1orglaugh:
You could sign up to AFF and just promote their friendfinder offer, or promote one of azoogle's dating lead gens. I think AFF also has passion.com, which should be ok (but I don't know for sure.)
In my own personal experience, dating offers suck when promoted on general traffic sites. The first time I promoted FriendFinder on a gaming site I owned I ran it for like 6 months and got 3 free signups. Needless to say, I didn't know what I was doing. I'm still promoting dating offers through other means, best day I sent Azoogle 36 leads.
