Usually when a provider reports a fake review, TER admin reaches out to the reviewer to ask for proof he saw her.  Proof is usually an email, PM here or a text exchange.  Of course texts can be faked, but it is much harder to fake e-mails. That's why most reputable providers listed on TER have their initial contact by e-mail, so there is a trail.  Do you do that?  If the accused reviewer never replies, technically TER will usually take the review down, but I think you need to keep on them about it.

As far as being delisted, there are a number of good reasons that TER will delist a provider - LE issues, significant other issues or being outed to name a few.  Not being happy with a review, fake or not, is not one of them.  Since you have already announced to the world that's what your reason is, TER will likely not delist you, but I could be wrong about that.

All I can recommend is stay on admin for getting proof the guy saw you and if he doesn't respond, then the review should come down.  If the guy does send proof, they will let you know and you'll just have to do whatever damage control you can.

So, about those $300 pee fest dates.  How much notice do you need for something like that?  My dog is into that sort of thing and he's got a birthday coming up.

Just kidding.

All I got so far is he said he saw you downtown.  Where?  Whem?  Where is the email or text?  My website clearly states what my rates are and they definitely are not 300 for two hours and my website clearly states that I only give golden showers not receive and NEVER would I drink someone's piss and I have never done a golden shower anywhere besides my incall nor have I takes a shower with a client outside of my incall.  Why are they allowing all this false info to stay up about me?

The guy, with screen name BS X 2, is too farfetched to be believed. Your rates are well advertised. His self-aggrandized claim of 300 special is telltale of the fake.  
I'm generally most appreciative of all providers who give their most intimate body for our enjoyment. I see the benefit of doubt in your favor. This kind of jerk, obviously a misogynist, who takes women as goods or tools, should be granted "premature ejection" from the community.  
Fight on!! Hope other hobbysts will chime in their support.

towards providers that don't drink piss, so that is a good policy as far as I'm concerned.  

Sometimes you need to follow up a few times on the problem reports.  It might also help if you got a few of your other reviewers to file problem reports with the reviews as well, labeling them as fakes.  Several months ago, multiple reviewers spoke up through problem reports about a fake review that claimed a girl gave them BB anal, and after enough complaints, TER moderators finally removed the review.
