I've always tended to the opposite, to try not to telegraph that I know men are there at a distance, but watch them surreptitiously. I have ditched someone who was following me once that I know for sure, and once when I suspected they were but couldn't be sure, both times in urban areas.
There was an occasion, many years ago, when I was surrounded and physically harassed by 5 or 6 men on the street. I remember acting without any conscious volition, watching the scene from a vantage point a few feet behind my left shoulder -- weird sensation, that. I got right up in the leader's face and screamed at him, and punched him in the chest with the blade end of a screwdriver. (At the time, I had a junk car that had no ignition switch; the screwdriver was for starting the car.) Seems I was aggressive enough to make them reconsider, because when I turned and slowly walked away, they left.
