I'm looking at the Ad Board and there are a number of providers advertising, but with no reviews. I don't think they should be able to advertise if there are no reviews on TER. Also, if a provider is delisted can she still post on the message board?

A girl has no real control over whether she gets reviewed. Especially these days. Why should she be penalized? Also, considering the shape TER is in these days, it needs more people advertising, not fewer.
That said, I can't imagine booking with a girl who had no reviews unless she was recommended by a friend who'd seen her.

I’m a perfect example of someone on the board with “no reviews” but that is by choice which I have explained various different times. I’d rather pay for a membership vs people knowing my business in who I see and what I spend as well as the couple times I tried to review in my younger days, according to TER I couldn’t get “graphic” enough nor “detailed” and had me rewrite it several times until the point of just giving up. So I would rather just pay for the membership and move along and enjoy the site.  

If a provider has a "no review" policy they cannot be listed on TER. If they are a provider member and just happen to have no reviews, that's OK so long is they permit themselves to be reviewed. This is a review site, after all.
Whether you choose to review or not is an entirely different matter, of course.

What better way for a provider to actually GET reviews than by advertising on a TER board/s?  

If a provider doesn’t have TER reviews yet, what better way to generate business with reviewers than to advertise on TER?

Good reviews drive customers to see providers.  If a provider has just as many bad reviews as good ones, she should learn how to "fake" the chemistry.  Most excellent providers will have some outlier reviews that are not as good as the majority of her reviews. These do not affect their business, in my experience, because those of us using reviews to choose ladies to see know that there are some reviewers that weaponize their reviews for various reasons.  Its normal for any provider to get SOME bad reviews.  Not everybody is a match for a particular provider.  More experienced mongers will be able to look past the failed chemistry aspect and concentrate on the two main criteria for a review, i.e., looks and service, but again, if you can fake the chemistry, you will add points to your reviews, but most guys won't know.  We are paying for a FANTASY, not a reality, so whether you "connect" with us or not is of no import as long as you are engaging, playful and fun.  This can be entirely staged by you and lead to a great review. No need to "get real" with a guy paying for pussy and risk getting a bad review.  Just my opinion from seeing hundreds of providers.  

She would have to back that up by asking TER not to run any reviews of her.

If she has a written "no review" policy on her site AND TER becomes aware of it, that alone is enough for her to be de-listed and for her to no longer be able to take advantage of TER's free advertisements  

If she simply tells people not to review her, that means nothing. If she has it written anywhere on her website or an ad, then a problem report from any TER member, with a link to that info, will automatically get her delisted.

Yes this is head scratching, but google still works well with a name or number typed in.  I see a few of these ads up, and some ladies have TER linked to their P411, while others don't, to each his own but with the prices these women are charging I am past the TOFTT approach.  There are new mongers that stumble upon TER all the time that quite simply don't know any better, and these women prey on them, just my opinion.  Idk when TER became the villain in all this, but my outlook on it is if you're charging a service and there is an avenue to which I can get an idea of how good or bad that service is before forking over my hard earned money then I want to read about it.  Back in the BP days I could afford to TOFTT, at $100 if the service sucked then it's "oh well, that didn't go well" and move on, when the coin gets up around or past $300 I'm not taking those chances.  

That a lot of these girls not only have zero reviews, have zero care about getting reviewed and I guess the new going rate is anywhere between $600-800 per hour but I’m also finding the they aren’t PSE nor even GFE. I’m talking about the new generation of girls out there between ages 23-30ish with the Kim Kardashian asses and if you follow them on Instagram or snap they have pimps now. Give me the 45+y.o. And I’m so good with them.

Well, that is the problem with so few quality providers. I've found that increasingly if there is a hot and good provider, guys don't write reviews. There is such a scarcity of young good looking and good service, that you're getting a hoarding mentality. Also, the "if I'm spending that much money, other guys can go figure it out on their own and not on my dime" attitude. I can't say I blame folks for it. It is a downward spiral. I will sometimes try out an agency girl who has zero reviews over a two week period. Often, she is above average and a good value. Once one review is written, though, then the flood gates open for more reviews, because the secret is out.
