I agree with this theory. It's pretty clear to me that all the characters know of the cameras. (RLC itself says that the hosts know and that it would be illegal if they didn't; I would think this would apply to the guests, too.) Some of the sex scenes involved the hosts deliberately keeping the bed cover over themselves--clearly desiring to avoid the camera at the time. RLC probably suggests that the people wear sexy clothes (or be nude) but tells the couples to avoid nudity and sex generally in the free rooms--so that viewers will pay to see the bathrooms and bedrooms. I doubt that in real life they would wear such sexy clothes as much as they do in RLC. They must be paid based on getting viewers to view them--and they probably get paid more based on revenues generated--which means doing things in the bathrooms and bedrooms.
