Surely everyone interested in porn is facing a "no more room in bookmarks" problem, not a scarcity problem. The market is so saturated profitability of porn sites has dropped to less than 10% what it was three years ago.
Even industry leader Danie's Hard Drive is feeling pain. Coop payments and bounties are down to just about nothing. Internet trade magazines that were praising the business methods of the porn kings (and queens) are now profiling the scramble for profit - any profit at all.
With an absoultely endless supply of 18 to 24 year old whores, I suspect modeling fees are hitting rock bottom as well. This will not affect supply, because millions of young women will do absolutely anything if there's a camera pointed at them, paid or not.
