Seriously why would you even ask, you can get all that shit free, who the hell is going to do a $1 signup when the second link has more niche specific videos then you could ever watch in one year...
I think it's kind of funny you'd even think you get anything off that, here's my top results for your first keyword:
www.pornhub.com
www.slutload.com
www.spankwire.com
www.thelatinateen.com
xhamster.com
and anyone is going to join a trial, lol... state of the industry folks, you have to find others way to make money, you can't just "promote" a program anymore using old techniques
