No. As I understand it, porn sites depend on recurring subscriptions that people forget to cancel. If it were overuse and undersubscription, they wouldn't be profitable.

This is true. As I said in the porn thread, I used to work at a large porn company. One time we had about 3 weeks of significant intermittent downtime, due to a really bad server migration.

I suggested that we send out an email to the subscribers offering a one-month credit if they wanted it, and the management looked at me like I was crazy. When I asked why, they explained that if we sent an email like that out, it would remind the members to cancel their subscriptions.

That was a big part of my inspiration to create the "iTunes Store for porn" application.
