Interesting perspective. It's important to note thought that VH and VV are designed to be more "yeah we know the cams are there, and yeah we know you people want to see us fuck a lot and play for you". The other sites are the same, just not quite as blantant about it. One could make argument that all the tenants are prostitutes, in the same way porn is a form of prostitution. Like I said, VH and VV are just a bit more upfront about it whereas the others want to try and pretend that they are displaying their real lives behind hidden cams.
