I've never seen a hint of such a feature on TER.
Sometimes I can spot an unreasonable review based on its being way off the norm.
I recall reading one just a day or two ago where the guy pretty well put himself at least partially at fault for the bad experience.  
So I kind of like the idea of it, but it's hard seeing TER putting in the software investment to make it happen.
One motivation might be that it would help the ladies get more involved in TER, which could be a Good Thing.

If you're interested, I've posted the link to the "Suggestion and Policy" discussion board (in case you'd never seen it) and I've no idea if the site operators engage much there or not, but you could post there what you've posted here and see if there's any action.

(No reviews from you for 10 years?  Dude ... get some nice ladycock!!!)

My 2 cents:
1) TER does try to follow up with providers, if they can, still have  the same contact info etc. I've had several reviews that were not approved becasue the provider didn't agree with something. It wasn't always a bad review, sometimes it was that I said they gave BBBJ or went raw or gave DFK and the provider didn't want that info shared publicly. I could have possibly debated them but why waste more time.  
2) TER also has a list of banned providers from the site. They don't tell you what the reason is, they just say that they don't post reviews for that provider anymore. It's happened several times.  
3) I made a comment on this board a while back about guys who have 8-10+ trans reviews, giving them a performances of 5-6 and below, but the genetic escorts they reviewed where all above that. The trans girls that they scored low, regularly had performance reviews above 6. When you read the reviews it's like they expect each trans girl to look like a top pornstar and perform like it as well. I was essentially told to shut up lol... Yes, some guys are just being an asshole and trying to hurt a provider who didn't perform to their expectations. Much of the time I think these guys have some anger management issues that cause much or most of the problem with a provider.  
4) I've found the girls (cis and trans) who have consistently average and above average reviews to be just that. Keep in mind there are less and less reviews overall these days as the culture changes. Also, keep in mind this is not a business that has guarantees, money back incentives or a customer service department to vent your complaints. This can be a ruthless environment, remember that while you're tying to live out fantasies...    

To hell with all the over thinking, some ladies are professionals , most are rank amateurs  only   In the business to rip and run.  Unless they are highly reviewed they can occupy a street corner. Only fan has turned many into hustlers. Egos are getting a little stretched, to many princesses

I take all reviews both good and bad with a grain of salt. I tend to be especially skeptical of the negative ones and feel like they tend to be one of or a combination of the following: the client was going in looking for things wrong; they client had ridiculously high expectations and thinks money entitles them to anything, the client doesn’t see providers as people; and/or the client has some self loathing issues about being attracted to trans women that need to be addressed.  On the flipside some of the positive ones read as people writing out fantasies, reliving the ego/power trip they exerted over the provider, or use just flat out gross language.  

I read reviews mostly for verification of existence and occasionally performance. The ones I write are for the providers and I ask beforehand if they want me to. I’ve had great experiences with negatively reviewed providers, and even greater experiences with unreviewed providers. I’ve had some lackluster experiences too, but none to the point where I felt the need to write a bad review. The only instance in which I would consider writing a negative one is if my personal health/safety was threatened. Nothing good comes from talking shit about people on the internet, especially in situations like this. I just take it as a learning experience and kept it moving.  

It’s really easy to get a general idea of how someone is if you treat them with respect when reaching out to them, but that seems to be labeled as “simping” around here.

Its important to check out a reviewers other reviews.  
If its thier only review, i dont usually trust it.  

We also have an issue with the looks rating. While yes, it is subjective, a provider like TS Ednita, is not a 9 or a 10, no matter what angle you view from or how buzzed you are.  

Just be honest in the review, if the service was solid, say so. If not, say so
 

The idea that we should only post postive reviews doesnt do any of us consumers any good at all. Its actually a foolish idea imo.

This business is very subjective. As others have said, research the reviewer too. I think it's also important to realize that a reviewer may have caught a girl on a good day, or a bad day. If I'm honest, the only thing I find reviews helpful for is knowing if the girl who opens the door will be the girl in the photo. Everything else is up to us. As for review rebuttals, I hardly see girls giving a shit. Over time, the good ones will get good reviews, and the bad one will change their numbers, so it really doesn't matter.

I posted a very lukewarm review of a provider and she contacted TER and asked for them to contact me.  I would not classify this review as negative per se; this was a YMMV type review.   The provider wanted to know, among other things, where we met, when we met, and what my phone number was.  I was unable to provide all of the exact details she requested, and I refused to provide my number.  I usually wait a number of weeks before I post a review, and I also delete texts from my phone unless I plan to repeat.  I gave TER everything I could and, to their credit, didn't just take her side.  I explained why I wrote the review and they let it stand.
