The two guys who visit Elettra and Raniya they will have know from the start about the place having live feed cameras 24/7, along with a team monitoring these cameras.
Also this villa / area / site there will be someone on site from rlc, to do risk assessment on people coming and going along with take the legal info need for Elettra random guys she fucks.
Also there is some form of security on the site from my past experiences normal some private company.
If you email rlc they will tell if you appear on camera you need to sign legal paper work for this to happen. Spend a little time search google about starting to do web camming and you will see the process these site use.
Reason why
First: my best experience as developer / technician at another similar style site, anyone visiting even not for sex has to sign waver / agreement there fine to be record. These contracts also state the cameras can record 24/7 with night vision albites and things.
Second: When running adult cam site even if your just talking for record keeping by law they would have had to take copy's of id / documentation. Think of signing up to work on a cam site, well that same process apply's rlc. They can't appear on camera with out sign these legal documents as rlc can get in to major trouble.
