The fact that the first reviewer completes the provider information often leads to inaccurate, incomplete, or malicious details.  The difficulty changing that information once it is set disincentivizes updates.

The problem on the hobbyist side is clearly bad info, which can lead to bad reviews and often the claim of bait and switch.  This issue also renders the "Search" function nearly worthless as some key factors could be wrong or not included.  Some examples -  

I know a provider personally who is 26.  Yet her first reviewer was not happy with her and listed her age as 36-40.  Nothing wrong with 36-40, but the impact to her is exclusion from searches for younger providers.  This has a real impact on her business and since she works for an org, changing the details are a hassle.  Another issue that I encounter is inaccurate info about breast implants.  I love natural and therefore tick that box on my search filters.  The returns cannot be trusted as many reviewers can't tell the difference, or guess wrong, or select "Don't Know".  I realize reviews usually indicate MM's or not, but the problem is search results that are filtered out erroneously.

My suggestion - Have a system where reviewers can update a "Don't Know" while submitting there reviews.  Have a process for reviewers and providers to update incorrect information.  I realize this exists, but the process is not simple.  

Disclaimer:  If I am wrong about the process to edit/update provider information, I apologize.  Also, if I am the only person this bothers, well then never mind.    

On the first point, you can ask the org (who is, I assume, the current correspondent / owner of the Profile) to request TER changes. Also, it has been known that an org will give control of the Profile to the Provider herself. (Some orgs will NOT do that, even when the Provider leaves the org for another one or even goes indy. That's kind of mean.) Once the Provider is the owner / correspondent of the Profile, she can make the requests on her own behalf.

All those other issues? Fake / real boobs. Real / imaginary age. ... Most of us learn to read the text reviews as backup and corrections to the Profile data fields. "Profile says fake but you'd never know it!" and so on. Likewise, when searching, we learn to loosen up the parameters a bit. Oh ... about age and the you know that she's 26 yo. How? Did she show you ID? Real ID or fake ID? You read it on her website? I can think of a popular Provider is listed in her late 20s but she is in her 40s!! She has changed her name / persona several times over the past many years, getting younger each time!

The amount of wrong information on the profiles is staggering. That’s real and it’s very frustrating.  

 
Nobody has come up with a way to fix it that won’t lead to more misinformation.  

 
If everyone had good intentions like you, it would be easy. You can see how making changes easier would invite more BS.  

 
They could reduce the number of “don’t know’s” in the profiles by rejecting first reviews with more than x of them. But that would discourage people like you who just want to get as much of it as possible correct, and encourage the BS artists who don’t give a flying fuck.  

 
They could require every review to go through all the fields of the profile like a first reviewer does. Same problem as above. Also they’d have to hire four hundred thousand mods to sort through the disparities.  

 
I’m really frustrated by all the wrong profile fields too. Never seen a way to fix it that didn’t look like one step forward and three or more back.  

 
Just keep fixing what you can. We appreciate you for that.  

 
Making updates easier won’t fix your search woes. Not enough people would do it. ImpPoster is right, you need to loosen up your searches and spend time sorting through the many results. It sucks. Make use of the add to favorites button.  

 
If you like the pics and several reviewers say pics are accurate, why do you care how old she really is? Put in the time looking at ads and reading reviews.  

 
Changing age down is probably the hardest update to make. If several reviewers say something like “no way she’s that old, she can’t be a day over 30” you might be able to get it done without going through the org.  A green check on her P411 would help.  

 
Don’t get me started on boob size and authenticity around here! It’s rarely right. I think it’s wrong more than it’s right. If you’re searching by that you’re probably missing out on a lot.  

 
They need to change the field that just says “Pussy”
The number of profiles that incorrectly say natural is insane.  
I swear there’s a bunch of idiots here who think that field is referring to whether she was born a biological female.  
“Duuuuhh I don’t thunk a ser-gen coulda builded a volva dat nice, ima click on nature-all”  *unibrow intensifies*

 
Needs to say grooming or pubic hair or something!
