Just stumbled over this thread.
I had a similar experience some time last year.
I still have the messages.
She was based in Reading at the time, I called and arranged a suitable time, all good.
A few minutes later received a text stating "Sorry following my security checks I will not be able to see you."
Me "Sorry to hear that. Was it something I said"
Her "Not at all, I use a national database for escorts to check safety of all clients before giving out location details, someone it seems has had cause to enter your details in there as a potentially dangerous client. Sorry but I don't negotiate when it comes to this."
I explained that I use Adultwork, ukpunting and another site, and have never had any issues, but I understand her concerns.
She responds by saying it was on national ugly mugs.( I know I'm not pretty but that takes the piss!)
I thanked her for the info, and left it at that. I was a bit concerned as maybe someone did indeed think I was dangerous, so checked the website, and she must have fabricated the whole thing, as none of my details appear there.
I just left it at that, and a lucky escape from what seems to be a time-wasting girl.
