There is an endless supply of free porn on the web. IT WILL ALWAYS BE THERE. The only thing that can be done is to start scaling back. Most TGP's have more free content on them than the paysites they link to. Which leads to the ever popular: "why would you pay for porn when it's free?"
The trick will be not only "censor" some of the content, but to scale back the amount. A surfer knows with-in 2 or 3 pictures if they like what they see. I would have to think that the most annoying thing to a surfer is being ping-ponged from site to site in an endless sea of porn only to be "traded" around like a cheerleader after prom.
Give them a taste and if they like what they see they will buy.
People are not stupid, (contrary to many studies and observations
) -when they see what they want they pay for it.
