When you are posting a review, you are in fact posting personal information. You are basically saying that this person is providing sexual services for a living. I think that information itself is potentially more harmful to the person in question, rather than mentioning the fact about her opening business somewhere, without giving away specific location.
Anyways, let's not get off topic and turn this into an argument. If you want to have a debate about posting etiquette, I suggest you start another thread dealing with this issue. For now, let the mods decide what is appropriate and not.
Now, back on topic...
