IMO Keeping the site running would be easier than closing it down. If Deb is burned out being in front of the camera get another wannabee porn star to fill her shoes, buy in exclusive from content producers, buy in non exclusive for content providers (we have a few scenes suitable

)
Leave it up as an archive site or rotate the content, both excellent alternatives to closing it down. I'm assuming you are leaving up the members area or refunding all the members money if it comes down.
But as many have commented this did not make sense at the beginning. Debs we have Deep Throat Videos.
