I'm gonna have to disagree. I have no refrence as to the girl you are talking about, but your statement  

"experience tells me that website/lady are fake or too good to be true. Ask yourself, how could someone so attractive have no reviews and no other presence in the hobby community."

doesn't really work.

 
There are many reasons why a pretty girl in this industry might have little to no reviews.  I, for one, am new to the industry and still building my online presence and reviews. I've seen several clients, but many do not have time to write a review or don't go to/have profiles on the review sites at all.  

Missing out on meeting a provider because she's "too attactive to be real" is kinda silly. Especially if she has other social media handles and a personal website that all link back to her.

And your comment about "At her prices I wouldn't TOFTT unless she agreed I could pay at the end of the session to ensure I didn't get upsold or ripped off."

There is no "paying at the end of the session." You should have the cash in an envlope in the bathroom or a nightstand where your provider can see it and count it. Otherwise WE think we're the one getting ripped off.

Never heard of her. Looks like she’s touring.
