How am I going to know how many people saw the video of me being raped? If some anonymous person downloads the video, how am I going to know that? Better yet, if it is distributed via PIR like systems, it becomes essentially impossible for anybody to know the number of people who viewed the video. I already said in another thread, it is not somebody viewing the video that causes the distress in the person depicted, it is the possibility that somebody will see the video. After a video such as this is uploaded to the internet, the possibility for people to see it will exist regardless of if anybody ever does see it, and in many cases the person depicted in the video will never be able to tell if no people or a thousand people or a million people saw the video. It is the possibility that someone will see the video that causes them stress, and that possibility is independent of anybody ever looking at the video or not.
