Luckily people don't film in my gym, but watching Joey Swoll [1] I've seen plenty of idiots (often young women) who try to make someone in the background of their video look bad. It's always completely obvious that the person in the background (who probably doesn't want to be filmed) is not staring or being a creep, even though heavy zoom and slow-motion is used to "prove" something. Ridiculous.
