Can any attorney with knowledge of fair housing weigh in on this? Law quotes states that the ad cannot say these things, but the publishing of an ad in a medium targeted based on these seems like a relatively new ground, since the ad itself is likely fine, but how it is distributed is definitely not in the spirit of the law. In finance, I'm fairly sure zip+4 is off limits in many pricing models for this exact reason - it is too specific. However, I'm not aware of anything like this in advertising publishing that a given ad has to have a chance of being seen regardless of the protected categories. Regardless of the law, it's definitely extremely unethical to do this.
