You asked if she provided.  The guy posted reviews that clearly indicated she did.  You said nothing in your original post that would lead anyone to believe that you had checked the reviews, or contacted any of the agencies.  Now if you had said something like "Hey does anyone know if she still provides and how to book her?  I checked the reviews and none of the contact there work"  you might have gotten different and better results.  Don't fault someone for answering the question you asked and not being able to read your mind.

And, yes, I'd say laziness was involved.  It took me two seconds doing a google search to find the link below.  Since she's advertising an upcoming trip to NYC and lists a different email address, one would presume that the email address in that ad, as well as the phone number, are valid ways to book her.  

Maybe it's your approach that's the problem and not just laziness?
