@TeamYouTube I got a COPYRIGHT STRIKE from someone I had written permission from. 6 days after publishing the video with his clip in he /w me: "Please do not use any clips of my channel anymore, thanks" and 59' later he issued a strike. Can he do that?!
From what I've seen from other creators, Youtube does not protect creators at all. It is highly likely if you appeal the strike it will be removed, but the other person will never receive any kind of punishment for a false strike.
