It does not need to be for a commercial product to be legal. A private movie would be just as legal as a commerical one. But I don't think Derrick would book girls for phony POV out of business reasons. i.e. a PSE goes for $1500, a POV goes for $1K.

But lets get back to the question that everyone has asked you. Why do care? If Derrick is doing it, I'm sure the other agencies are as well. Why do you care? It porn, not Morgan Stanley, I'm sure you didn't get involved in porn cause you wanted to deal with only the nobleist people.
