I find that many of us face the "how to rate" conundrum. For some, it may be easy. For me, being honest, it's only easy when the provider is near perfect. But more often than not, there may be some flaws. What makes it hard is these are people, not some product you can find on Amazon or eBay. They have real emotions and can be impacted by what we write.

 
I find myself not wanting to be overly critical, especially if she is nice and delivers in the service department. I cannot so easily be as tough with a provider's review as I can with my thoughts on a TV or restaurant. The less I emotionally connect with a lady, the easier it is. But if we connect emotionally, I'm now more concerned with how I might make her feel.

 
I once met a lovely young lady who had returned to providing after a 6 month hiatus. Her reviews were top notch. But one reviewer slammed her. In the services department, she was amazing. But in the looks department, she's what I would consider a niche that isn't for everyone. I can see how some would think she's beautiful. Yet, others would be very disappointed. And, once a client gives off that energy, I'm not certain her services can save her every time. Anyway, this review really hurt her and she became depressed over it and this is why she took time away. It was a reminder that our reviews can have this impact on providers.

 
I know some may say this career isn't for everybody and if she cannot take it then maybe it's not for her. I can't disagree more. I say this because one of the most disappointing things we encounter is providers that feel mechanical. When they lack emotion it's hard to enjoy the session. But when they feel real and emotionally connect with us, the sky is the limit. And when I meet one like this, I might inflate her a little bit.

 
I do my best to be honest. I don't just give out high marks. But I also don't follow TER's definitions. I openly participate in the rate inflation that exists in TER. And, I do so more with ladies that show they deserve it. And, while this might not be the popular feeling amongst everyone, I do this unapologetically.

 
That said, let the berating begin!

so the honest thing to do is say whether or not she looks like her photos, or looks better, or not so much.

I agree! You chose her based on her photos. Others will see her photos. If she looks exactly like her photos, or better in your opinion, you should rate her very high. If she looks older or fatter or whatever standard made you feel she was not represented honestly, then you should ding the rating.  There is no universal standard for beauty. What is a 10 to one guy is a 4 to another. So you cannot really assign a number to describe someone. At best, or worst, you can just give your opinion. It is more fair to rate her based on how she represented herself and if she delivered.

There is no point in defending my support of your post.  There will be those who adopt a 'Client Code' mentality (write critical reviews to benefit clients, regardless of the impact on the provider).  That said, In general, I believe in the 'Client Code'.  Reviews should be written to benefit potential clients.  But, they can be honest, without being hurtful.

 
There are a lot of ways to judge the quality of a session.  It is not all 'how much did she fulfill my every sexual fantasy'.  The session can be judged on appearance, expressiveness, engagement, connection, sincerity, etc.

 
I try to honest, while focusing on the positive aspects (assuming there are some).  I'll mention the things that occurred that I really liked.  And, omit things that did not happen.  And, if there are things that didn't occur in a session, or were less then stellar, the review that I write which does not praise those aspects, will provide a signal to prospective clients as well.

That’s fine. It’s the average of ratings that matters. People are always going to rate based on “how they felt” in the session(s). Your feelings for her deserves a score too. So I don’t see any harm unless you are just making things up. 8->9 is fine. 7–> 9 or 10 is not okay IM0

The only feelings im concerned about when posting hooker reviews on a fuck board is the gents that are slapping down their hard earned cash.  

My reviews are unbiased and extremely honest. Beaver stinks? Breath stinks? Ass stinks? Poor bbbj? Poor sex? Provider had a tick? Provider has tourettes and makes Brando impressions when you stick it in her ass?  

The reader is gonna know. Honest reviews are the best. Only a big pussy wouldnt write an honest review because they cant handle their emotions.

The TER review form includes a field that asks whether the photos are accurate. If we follow your suggestion, once a reviewer has answered that yes, I guess it's up to each player to decide whether the lady in the photo looks like a 10, 9, 8, etc. I kinda like that idea.

Of course, there are some ladies posting photos that don't show their faces. That would require the reviewer to make that judgment, and for the rest of us to determine whether her or his judgment is similar to ours.
