I put a simple search with only body type and height in.  The results came in by most recent date.  1st result reviewed 1month ago.  by the time I got to the eighth review the results came back with last review 3 years ago. No website or ad location for the provider.  Are there a lot of "stale" provider listings on ter?

Unless a provider is delisted/removed for a reason, they’re here forever. There are many very old profiles who have no reviews way longer than 3 years ago. There are ones that are from over 20 years ago.

unless her ad link is no longer good.  She could have changed to a no-review policy during Covid like a lot of providers did.  Generally, if her ad link is still good, she is still accepting business.  Otherwise, you will see a "Report New Link" message where the link should be at the top of her profile.

I have found that on free escort listing sites, girls who retire may not delete their page.  They just walk away.

 
However, if there is contact information, give it a shot.  Worst outcome is that you get ghosted.

…there’s the scraper sites that the providers have no control over. Stuff can stay there forever.  

 
There are also some paid ad sites that if you have a direct link, like on a TER profile, you will still see the ad even though she hasn’t re-upped in ages. Jensen or TRQ or someone explained it once not too long ago. Something like when a provider’s ad expires the site just removes it from visibility or something like that. But they don’t delete it so that if she shows up and pays again, it’s all still right there and the ad can easily be put back on the site.  

 
I believe agencies do the same thing with their gal’s profiles on the site, when one of them is taking a week off. If you go to the agency website and check the current “lineup” a given lady won’t be there if she’s not working today, but the link on her profile here will still be working.  

 
I just went and looked at the profile of a lady I used to know years ago. She’s retired. We had become good friends, I met her sister ffs; trust me, she’s retired. But the adultsearch link on her profile works just fine. There’s her pics and ad copy and everything. You can click on “info” on the ad and see that it was posted more than six years ago. You could spend all day searching the adultsearch site and not find her, but the direct link still works.  

 
This why I appreciate the ad sites that have “freshness dating.”

I appreciate that you may be looking for a specific weight and body type, but at least in most major markets there are plenty of providers to choose from if you just broaden your search. Also, I suggest you start broad and check the results, then narrow your search. In La, I am rarely stymied by old results and I usually have several provider choices with the general characteristics I am focused on at the time. The system is well-designed as the first results represent the providers with most recent reviews, and links that are no longer active usually say, “report new URL”. If you are in “pussy Siberia”, that’s another story!

I have a handful of ladies who I keep tabs on should they ever tour in my area. I have seen with multiple sites where their ads disappear from visibility via search. Meanwhile, my saved links still go to their ads on those sites. TBH, these sites are being a little lazy. There are other sites that also don’t erase the ad, but the link no longer works while they are not paying. I have seen numerous providers where their ad comes and goes - exact same link.  

 
As for scraper sites, like hot.com, IMO, TER shouldn’t allow them to be links on profiles. They are very misleading. Fine in the immediate when ads are active. But terrible in the longterm when ads go away, especially if a provider isn’t providing any longer or important details have changed.

I agree. I’ve thought that for a long time.

Some of these " stale accounts " are actually ladies who have gone " under the radar "  I still see one top 10 TER provider who deactivated several years ago. Luckily for me she still sees a few select guys who have been with her for years. I have traveled 1000s of miles out of my way over the years to stop in her city. Due to my experience with her I do sometimes send an email or text to providers who don't have recent reviews. Who knows what might happen ????

Agree! It’s free to ask , if the lady is around she will at least reach out .

Depending on the specifications you put in that might not be the best way to assess that though given the first returned review was from a month back and there has to be a bunch of more recent reviews.

 
That said, as mentioned unless someone takes specific actions reviews will stay. Not having a website or ad URL -- by which I assume you're saying "URL Not Found" (or whatever the text is) is in the profile area -- will depend on the provider and how they advertise. Some use agencies and tour so move around and the agency will update their webpage so TER will not longer be able to find the URL and remove it. Similar with some of the ad site -- provider uses them for a while than doesn't keep paying and the ad is removed. Older cases for a personal website could be as others have mentioned, retires or otherwise stops maintaining the site and it's no longer something TER can verify exists and can be accessed.

 
In some of the cases that will happen even when the provider is still active but no one has submitted a review with the updated URL info.

Before I understand TER better, I didn’t pay attention to the dates of reviews like I do now. I had one lady that was semi-retired. She was still seeing some longtime clients, but not actively advertising and pursuing new ones. But since I reached out, she decided to let me book with her. She was fantastic. Still one of my favorites.
