I'll summarise the results of the fake profile first.
On 27 June 2014, I registered a fake profile, leaving all details unset other than name, age and profile description ("A Few Words About Yourself"), which I set (respectively) to "Michael Michaelson", 70, and "I'm just here to check whether this site is a scam. Notice that "Michael" explicitly requested only scammers to message him.
My suspicions were aroused by my friend's description of the site: drop-dead gorgeous women everywhere, constantly sending him letters and chat pop-up requests, yet for every letter read after a lady's first, he had to pay ten credits, and ten credits likewise to send a lady a reply letter - instant messaging chats cost one credit per minute after the first three (free) minutes.
