When someone files a DMCA on youtube, he does so under the penalty of perjury, which means that if you file a false DMCA like on a video where you don't have copyright, or where the usage of your stuff is covered under fair use, you can be held liable for perjury. There was this big drama on yt a few months ago when venomfangx filed DMCAs against thunderfoot, and ended up having to apologize in a video so he won't be sued.
From memory that was a different situation. The fundie twit tried to claim that content that wasn't his really was his, IIRC.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
