Over the course of my career, I have had the misfortune of several fake reviews. In the past I have been successful in having them taken down because the reviewer in question could never provide proof that we met.  

First, to answer your question, yes there should be a time frame for the complaint to be addressed.  Really, you should have a little more control over your reviews to help keep them up to date and accurate.

Then the chances of him responding are zero. So have you attempted to contact this person using the same method he contacted you?

I have never met this person so I have no contact information other than his TER handle. I PM'd him and he never responded. He used me to get free VIP and when he was caught, he ran off.

So it's a pretty good bet he at least had VIP at the time she tried to contact him.

For only the investigative period. That way, if it is fake, it doesn't hurt the girl.

it is a nice idea, but they are not going to change their policies with only a few questioning them...it will probably take many other hobbyists to contact them about it to even make them consider policy change...another idea that was floated around was that the provider had to approve if they had an appointment with the reviewer before the review was posted...only yes or no to meeting but not what the review had said

Many guys make a determination to see a girl, at least in part, on her most recent reviews.  

Well I can see the problem with providers saying 'yes' or 'no' to the appointment but it seems unfair that a review could sit up for 3, 6, 9 months just because the guy abandoned his handle after he got caught posting fakes. The time limit seems especially necessary considering the free VIP for reviews.

you are implying TER could create a perfect system...........ain't gonna happen!  Anytime human beings are involved..........human flaws emerge.  Chances are...........TER has no consistent rules on this, so it is in their "too difficult to solve" pile...........and keeps getting minimal attention.

I found the same issue with a hobbyist.  After alerting TER admin..........they deleted all 20 of his reviews and banned him.

and in this case I think the onus is on the reviewer to justify the review. I agree that the review should come down until the reviewer responds adequately. For goodness' sake, TER holds new reviews for new reviewers and providers until they can be verified... this is somewhat similar IMHO

the default should be that the review would come down during the investigation. If the reviewer responds with his proof that the meeting took place, then it would go back up. If he cannot or chooses not to provide any proof, then it would stay down.  

On boards on another websites...

I have had a guy cancel because of the fake Dec 2015 review because he "don't want the whole hour oral only".. I'm like WTF! I told him the review was fake and he never responded. There goes that. :/

I've had 10/10's removed due to information that doesn't comply with the way I do things. There was one fake review that has been taken down stating that I arrived at an outcall wearing a mini-dress and heels and we drank a bottle of wine together. The review was overall positive although it didn't happen (well, maybe in the guy's imagination...)

Your original post didn't mention that you didn't have any other contact info.  Maybe I re-read it?  I completely overlooked the fact that a review gets you 15 days of VIP status.  I don't generally write reviews unless I believe it's worth doing so for various reasons.  I have one review that I'm the fence about writing, especially due to the circumstances surrounding it.

This review randomly showed up and is very generic, it doesn't even mention my name or any physical characteristics. I PM'd him per the protocol because I had no way of knowing who this person is. It's not a bad review but it isn't consistent with my other reviews or scores.  

I don't think most guys here believe girls, in general, are " hustling them."  Are there "many", we'll maybe but what does that even mean?

I agree.  
I'm sorry but I refuse to believe a high volume girl remembers every guys she sees.
Last year while traveling I saw a girl in my hometown  
She decided I hadn't really seen her, TER jumped in and since it wasn't my base city demanded proof
I suspect she felt pretty stupid when I described her decor, where in the house her work room was and what her two cats looked like

Can they send him an email?

If all she has is his TER handle, then high probability the review is fake.  But then again,  I've meet a few whose only screening method was by my TER handle.

Keep this in mind, many read more than one review and sometimes we disregard a review for various reasons.  Sometimes the vibe isn't there between two people, other times its not consistent with what others may have stated.  So while it may be bothersome to you, I wouldn't get overly concerned

The guy wrote a fake review & gets 15 days free VIP. And doesn't log in for 14 days & counting...
Where's his upside for writing the review?

Well I'm assuming he did use his VIP. He got 72 hours when I contacted him. He probably didn't pay me much mind. But once TER admin contacted, I assume he realized it was more serious. I don't actually know if he logged in, I can only take TER's word for it.

How does one prove they saw a hooker? I can say I did she can say I didn't. Seems like a lot of he said she said to me. It doesn't matter what the trick says. If the hooker doesn't like the review she will deny it ever happened. Isn't the whole point to leave as little proof as possible of illegal activities?

Maybe saving emails and text/call log screenshots? That doesn't verify a session occurred but it does build a case.
Often there's some confirmation calling and/or texting, so the provider would then have to explain why she texted you a room number but then cancelled before you got up there

I communicate only via email or P411 so there would be proof of us setting the appointment. It has nothing to do with me not liking the review. It's the fact that the review is not real and in the past I've had fakes where they said I did things that I don't offer. This review is so generic that it's not bad but it is my lowest score of any of my reviews.  

I had a case where it was not even a fake review but a guy who had seen me and, to ensure my performance score wouldn't be downgraded, mentioned Greek in the review.  He didn't say it happened during the session or anything, but rather suggested that it *may* be on my menu.  

I think if there is anything consistent with the TER admins, it's only that they are completely inconsistent in how they run this place.  I don't know if it's favoritism, incompetence or disregard, but it seems to be a free-for-all.  

Another, and maybe better question, is just what are they doing to vet the review before it's put up?  It can be a 24+ hr delay from submittal to posting.  I kinda thought they were checking something...

...it meets the requirements as stated by TER for submitting a review. They don't do any checking to see if the session actually took place. How could they? Unless someone disputes the review it stands as long as it meets the submission requirements.

...click on his handle. If he has other reviews they'll be listed there. Contact the other providers he has seen if any, ask them if they can offer any insight.

I already did that. The provider that he reviewed the month previous to my review told me that she did not see him because the details in his review were not consistent with her incall nor the services that she provides. However she told me she had no interest in disputing the review becuase he gave her 10s so it got me nowhere.

the profile says BBBJ and the text in several of her reviews, especially if it is the most recent reviews, says CBJ I send a PM to several of the reviewers to ask what might have happened.
