I've  personally met this client, it was actually a week after he had met Russian Barbie Doll and he didn't have anything positive to say about her. Hope it helps.

As far as their websites being identical, a lot of escort websites offer free websites to escorts. They're usually simple templates you just customize. There's even prefilled out text boxes if you're  lazy and not creative. That's  how I got my website and I've  seen others that look pretty similar, maybe that's  how theirs look identical.
