Did you post that information in your reply to me because you thought I already had it? Of course not. You have shared that information with someone who didn't have it, and certainly had no need for it.
You've done something that the guy with the billboard didn't do. If you can't take responsibility for it, you should probably stop doing it.
You've gotta be joking. This is public information, it is not protected by the same right to privacy. I suppose you would agree then, that every time someone posts a thread with a news article in it, he is violating the privacy of all persons involved in the article?
