It's the new adult porn biz formula.
The math is weird, but it works kind of like this...
Spend $100 on tube advertising, then lose $5,000 in sales thanks to free tube traffic.
It's a new plan of some sort, where the big industry "players" try to make money from within the industry now, since there are no longer outsiders who are willing to pay for any memberships anymore.
It's fun to watch, if you have a good sense of humor!
