Chances are, they're a bunch of pimped girls that are "toured" around the country. I have a saved search on AW and refresh it from time to time to see if anything new turns up, and quite often 3 or 4 girls will turn up, all no feedback, new profiles, all working from the same place, often with similar phone numbers, and very similarly written profiles.
I did go and see one once, after an arranged punt didn't happen, and it turned out to be a bait and switch. I was a little naive at the time to clock on to the fact it was a pimped troupe, nor about the whole bait and switch thing (although it was very clear when I arrived at the hotel room it was a completely different girl). Turns out she was better looking that the girl in the profile, but it still turned out to be a shit punt.
