3fn or avnads for adult traffic?

I have some adult sites I want to promote, I tried an adult dating site on avnads, spent $15 on 1000 clicks and didn’t get any sales, got a few free sign ups, but not any sales. Should I try 3fn? Only problem is that they require a $100 deposit, which I’m not sure if I want to do. Should I start a campaign with about 10 different sites and spend that $100 in one go? I’d rather test a campaign like this instead of waiting for conversions.

Thanks
