This site is a porn ring scam. It's a part of a network of scam sites including xxxblackbook.com, sweetdiscreet.com, and about 3 or 4 others. The "members" are all fake and the fake profiles are actually people recruited to scam you. They get paid for leads and if you sign up for any one of the other sites. After some conversation and photo sharing (of widely circulated cute girl images) they lure you into making credit card purchases on the ring of sites, saying that the information is just used to verify your identity and status on another site. Of course this is bull$#*!.
Currently going to fight a series of purchases that's basically throwing money away, after a recent terrible laps in judgement. Stay away who knows what else is in these sites in terms of phishing and malware.
