YSK: If you appear in a YouTube video without consent, you can submit a privacy complaint and YouTube will take you out of the video.
Why YSK: There is a trend where public agitators are getting in people’s personal space in shopping centers and post offices, yelling profanities at innocent people in hope of getting a reaction. Their whole aim is for you to touch their camera equipment so that they can pepper spray you or for the police to unlawfully arrest them, so that they can sue the police department.
I saw myself in one of their videos and filed a privacy complaint on YouTube with timestamps and within a few hours, YouTube removed my footage from their video.
