In most states, you can be sued for publishing private facts about another person, even if those facts are true. The term "private facts" refers to information about someone's personal life that has not previously been revealed to the public, that is not of legitimate public concern, and the publication of which would be offensive to a reasonable person.
Oh wait, I see where you got this:

"In most states, you can be sued for publishing private facts about another person, even if those facts are true. The term "private facts" refers to information about someone's personal life that has not previously been revealed to the public, that is not of legitimate public concern, and the publication of which would be offensive to a reasonable person. For example, writing about a person's HIV status, sexual orientation, or financial troubles could lead to liability for publication of private facts.
However, the law protects you when you publish information that is newsworthy, regardless of whether someone else would like you to keep that information private..." [Emphasis added.]
Information on how to avoid being scammed by a scumbag is certainly of legitimate public concern and is newsworthy. Wouldn't you say?
Also, if you continue to read beyond the headline you will learn that, for liability to exist, the release of private information must be "
highly offensive to a reasonable person of ordinary sensibilities." [Emphasis added, again.]
Since an address is a matter of public record for anyone with a mortgage I don't see how releasing an address could be considered highly offensive to a person of ordinary sensibilities.
Isn't it funny how every scammer scumbag also thinks they're a lawyer?
My suggestion: Don't worry so much about making idle threats of frivolous legal action. Worry more about when the police knock on your door.
