Hey @TeamYouTube @YouTube why is my review getting blocked worldwide when the clips I used in it fall under Fair Use? Could you please solve this issue? #FairUsepic.twitter.com/z1zCy8hepJ

Fair use can exist on YouTube, but the ultimate determination of fair use usually needs to be worked out between the uploader and claimant, sometimes in court. Defending fair use starts with the Content ID dispute process. More here: https://yt.be/help/claims-FAQ
Nevermind. I re-uploaded the video by editing those copyrighted parts and everything's fine now. Don't wanna get into the disputing stuff, especially since it is the claimant themselves who are the judges. Thanks for your help!
