I'm going to keep a video of somebody up on youtube
Why do you think that it should stay up?
People should know the person they follow is a true asshole.
I respect that you want people to know about this person, but that's a bad way to do it.  Not only is it wrong to take a video of another person without them agreeing to it, in most cases it's also illegal!
It's fine. Everyone wants to watch it anyways, it would be a nice morale booster for everyone.
It could get you into trouble though! I just think that it is not okay to take a video of a stranger without explicit permission.
