Thanks for the tips
Looks like Private are moving into the swinging scene too:
"Private wants to supplement its ad income with other new revenue streams, ranging from an online casino it is going to launch in mid-February to a swingers hotel that is scheduled to open its doors in Barcelona in July. The hotel is a first test case, but Milton believes that he can quickly expand to 100 similar hotels operated on a franchise basis that specifically cater to swingers. And he isn?t ready to give up on selling content entirely; part of the hotel will be an offer for a free stay if guests are willing to have their escapades live-streamed on one of Private?s pay sites."
