@TeamYouTube I just got falsely copyright claimed on 3 different videos for using the intro to a game. The person who claimed me doesn't own any part of the game, and it is saying I can't dispute it. I tried to and it said it failed. I've had this same issue in the past.
If you’ve already disputed a Content ID claim and feel it was mistakenly upheld by the copyright owner, you can appeal their decision from the same place where you previously have filed a dispute. Find more info under 'File an appeal': https://goo.gl/Fzm3EA
