I rock with rude.com I love it, but, I have a bit of an advantage. With close to 80,000 people on myspace, I can send them to my rude profile which is explicit, and they can join for free. I get paid for each person that joins for free. I have done VERY well with rude, and even did some ads in craigslist for a bit with them. Very good money. But, then, I've got tits, that's always an advantage when selling porn, I suppose.
Hope that helps!
Love,
Jax
