Thank you Fusionfan. I couldn't figure that one out. Anyway, they've been up for a while, just hoping someone can confirm they are real.

as a general proposition, if you do a google search on an advertised provider's phone number and/or e-mail address, it will lead to 1) registration on the provider directory of a reputable, established board, and if its an established provider, probably linked to one or more reviews; 2) other postings by that provider on other dates and/or other cities. That can suggest a lady is touring or, if posting in multiple cities around the country at the same time, a scam; or 3) no hits at all, which means an advertisers with no credentials whatsoever. Try that approach with the three ads you posted, and decide for yourself.
