I guess this probably isn't a new suggestion, but I want to express my opinion.  I would like to see some way to review unnamed providers.  You could use the phone number and/or the URL as the primary means of identification.
On the one hand, sometimes I see an unnamed provider and I would like to know if anyone else can tell me something about her.
On the other, I recently visited such a provider and was not happy at all with her.  I would like to warn others.

If you mean unnamed because she doesn't have a review on TER, that doesn't matter.  You can still review her.  Since you would be her first review, your review will establish her profile.

If that's not what you mean, please enlighten me what you do mean.

I often see ads on BackPage where a provider gives her phone number but does not give a first name or a handle.  TER will not accept reviews of such a provider.
I suspect some women deliberately don't give a name so they can't be reviewed. Others just don't know better.

Such as some on BP/CV which don't mention a specific provider's name. They may post a pic or two, but don't identify a provider by name.

However, without a name the review would may not  be useful because one would be reviewing a "place" as opposed to a provider in some instances and proper identity of a provider cannot be made.

Is on Back Page...

I hate those ads with no name.  How do you email or call someone, if you do not have a name to use?

was on the girl you actually meet. What has the ad got to do with this? Once you meet her, you have her name and her phone number, right? How can she be unnamed then? Sorry if this is a newbie-type question, but I don't understand.

Some providers run ads without listing their name. Of course he knows, but he can't post a review because the ad does not meet the requirements because there is no name on it.

Example: An ad says incall tonight and posts a hot pic and a phone #. No name. Won't pass.

An ad says incall tonight and posts a hot pic and phone # and says "Melissa" Pass.

I run into that a lot with AMPS too.

whether her personal, or an ad site, it necessary for the review to be accepted by admin.  Either one is ok, but one of them must be in the review.
