I have read the other thread, and it appers that it hasn't been properly combined yet.
Anyway, as Excon (as I recall) said, the realtor lied; there isn't much you can do about it.
In short, you have no damages.
As to your privacy concerns, you say that "license plate, car and address of our home is listed". So? The address of the home makes sense in a real estate listing. And I just don't see what's the matter with posting a picture of your car showing your license plate. Thousands of people can see that every time you drive somewhere. That doesn't tell those people anything about you.

They can't do that. If they try it, just send them away. Tell them to make an appointment with you next time. And the timing of the appointment is up to you, within reason.
