If I was attracted to her, I would have no problem booking the appointment if the other reviews showed she was to my liking.

You are correct on your 3 points. I've often had  more than what was on the menu as "reviewed" by other Hobbyists simply by being clean, very nice, and a good appearance.

Some stories I've heard talking with a couple of girls... guys can be nasty dirty creatures. So service is of course going to vary.

Are you sure this is the same lady?  OK, let's say you're sure.
Probably she took a break from providing.  I see this all the time...  very often has to do with relationships.  The relationship goes South & the lady returns to the business.

A lot can happen in a couple of years.  Are the pictures current?  

I'm not sure what I'd do.  
I might open a conversation & it would likely lead to an appointment.
I would not take a permanant PASS...  I might make a note to "HOLD pending new reviews".  

Taking a step back...  when I look at a review history, I look for consistancy.  Say average 7 with a + or - one.  So 6-7-8 range.  I don't disqualify for low reviews but I definately read the text to get a sense of why the low review.  As a matter of fact, I always read the reviews on the last (most recent) page.  I try to get a sense of what the experience is like.  

You're guessing based on the review number.  You really need to read the reviews.  You are VIP right?

There can be so many reasons for lack of more current reviews. Could be family related, had what they thought they needed, etc, etc.

You have good thoughts as to why there were bad reviews. I would check a sample of those reviewers reviews. Some just write bad reviews. I would see if there was some kind of trait.

But, I personally wouldn't pass if there was an interest. But, that's just me. or is it the little guy? hmmmmmm

I think that, for starters, you could come up with a better way of asking us than calling us "old timers"

As far as your question, I would pass until I see a newer review or two. With that wide of a gap and the relocation aspect it may not even be the same lady.  Reviews get hijacked all the time. A provider retires and doesn't keep an eye on her profile.  It's not that hard to pirate her name and reviews.
