I don't think that DB techniques are a crock, I think that the "BUSTING" part is. It is a misnomer. They tell you to keep right on "DB'ing" even after LBS is done and has finally moved on. Should someone like that continue to "BUST" what is obviously not salvageable?
"Divorce Busting" means your D has been busted. Otherwise, it seems more correct to call it "Marriage Busting", since the effort was unsuccessful.
