What's not being understood is how exactly all this free traffic is being monetized so as to justify the 100's of millions of dollars being invested...and the advertising that "Spunk Lube" buys isn't the answer...lol.
And you're getting away from the original question, which is:
When a freesite buys a paysite it has damaged, how does it then expect to convince people who are getting porn for free to suddenly pay for it?
