Yup, exactly what Bec said.

For our traffic, the best performing sites are more or less anything big cock - our minion will bite at just about anything, so long as it is huge (real or not)!

I've tried a variety of sites that I considered great quality, offered exclusive content, and, more or less, cared about their patrons, however, they performed very poorly.
The only thing that tells me is the site does not have any guys on the front page, with a huge meat stick!
I was casting the wrong kinda lure!
