I was considering this provider until I noticed she doesn't have reviews since 2007.  What does this mean?   Do you treat reviews that old like they are recent?

She might have retired for a while for who knows what reason, or just did not want reviews.  In either case, I'd be skeptical of seeing her, esp for someone that young.

Check out her phone number, see if it's current.  Use tineye or google images to check her pics.  DO YOUR RESEARCH!!!!

Unless things have changed you are not allowed to ask about specific providers here on the newbie board.  You should be asking about the lady on the proper regional board.

That being said, Is she running an ad right now or did you just find her on TER's review section?  She may be recently un-retired, she may not want reviews anymore OR her profile and identity may have been stolen by another provider. Proceed with caution.

NO, you don't treat that big a gap in reviews without a question.  She might have been unavailable for some period.  There's a serious risk that the pictures might also be from that time period (as with a local hottie I was watching).  
Without asking anything specific, you should be able to ask a Q or 2.   Without prying, you could point out the long gap in reviews & just see what she says.   (There's enough time in there for her to have gotten in a relationship, married, divorced, had children, gone to school, gained weight, etc)   The contact information in the ad is different than her profile on TER.  I don't think it would be out of line to ask for a couple of current pictures.

if it has been just a few months, let alone four years. More than about three months with no reviews and I begin to wonder whether she has undergone some change from the provider formerly described. Weight gain, attitude change, unfortunate turns in her circumstances--I've seen each of these things transform a once recommended provider in no time.

All of which aside from the question of whether this one is even in the biz still.

it's easy to overlook outdated reviews like you have done, because, unfortunately, there is no practical way to exclude old reviews from search results. The only option TER gives you is the 'New reviews only' filter, which excludes everything more than two weeks old--way too crude.

However, the default sorting order is by date (actually, online status, which is effectively the same), so by looking at just the top part of the results, you can get the same effect. Unfortunately, this means that there is no way to both exclude old reviews AND sort the results by rating, provider's age, etc.

Favorites list.  I enter my Favorites list & use the note box provided to summarize my interest or lack of it after researching her profile, web site, ads, reviews.  You need VIP to use this feature...  If your VIP expires, you can not add to or access this section but it does not go away.
I used the TER Favorites data to extract several ladies at a time for my bucket list...

I personally wouldn't see anyone that didn't have reviews within the last year or so. There could be a few reasons why the reviews stopped. She sees mostly regulars who don't post reviews, she has adopted a no review policy, or she could be using another name as her primary persona now.

Many things could have changed over the past 4 years with her looks or attitude.
