Ok, this is one of the gaping holes in the db method. There is no way that you can keep family or friends from finding out, unless you live in isolation from them. They aren't stupid, and besides, the WAS usually has a head start on this anyway.
You might as well get as much, as you are comfortable with, of your side of the story out. You aren't the one who's done anything to be ashamed of, so why should the WAS be protected from their own sh!tty behavior?
