My two cents here.

 Just from reading reviews it seems to be common practice to say whether the incall was at "a hotel," or "her apartment," but only in very general terms.  Don't identify the incall location or provide details which could be used to identify it.  That could subject the provider to harassment or worse if it is a location they use regularly, or their own residence.  

 And if the incall location is at a place of business which rightly turns a blind eye to how their facilities are used by two consenting adults in private, then the heat brought on them by the mention of their business in your review could put them in a difficult situation.

Mentioning the location of a provider's incall in a review is a bad idea, in my opinion. It gives out too much information, and adds absolutely nothing of value to the review.

I thinkthe answer depends on what you mean by "citing the incall location".

If your talking about the review mentioning a specific hotel or address, then I would agree. But if it was a generic location (e.g. downtown Boston hotel) then I don't see anything wrong with that.

The administrator was right, very few incall providers would want there location plastered on major boards for all to see not only for their vistors and own personal safety but for discretion .
IF she is agreeing to you posting her location, even after mentioning there was a potential risk, you should be weary of a second visit as it seems quantity vs. safety for herself and visitors are not important

Incall location is no one's business until.....

....an appointment is made. I was unlucky enough to get such a review, with a few other non-related comments (such as "She serves free tea", and "She pays her bills with this"-which isn't rue!!), and I immediately felt very compromised and actually unsafe. I had not enjoyed this client's behavior, and had decided not to see him again even before discovering the review!!
Even if the review wasn't talking about an hobbyist experience, I still don't want that information available to everyone!! There are wacko's out there in this world, and publishing my location is very risky...all it took was one email to TER, and the review was gone.
Perhaps we could publish the location of the administrator of the other board's home address...he/she should have no problem with that, right? Every business person should operate ethically, as their actions affect their customers!!
