Last year, I had a case where a woman cut me up in her car when I was approaching a traffic queue, so I told her not to do that. At the next lights, she was behind me in the queue and sounded her horn at me, so I turned and shook my head. Further on, she was stopped at the side of the road standing next to her car shouting at me, so I stopped and had words with her (very calmly). A couple of hours later, I got an email saying that someone had posted a message on my YouTube channel. It was her! She had tracked me down there and started haranguing me on there. I replied, politely explaining a few things, and posted a video for private viewing by her and "another user", who I suspect was her under a different username. A discussion ensued, in which she posted several lies, and eventually she told me to leave her alone and stop harassing her! Fortunately, we don't keep a rabbit, otherwise I would have been worried.
