I have a Big Buck Bunny upload to youtube (from some codec testing) and every couple months some copyright troll flags it and tries to collect advertising revenue, which also takes down the webm version of the video (because until recently youtube couldn't put ads on those). Fixing it wastes hours of my time and youtube never stops the trolls or even responds to my requests for information about them so _I_ could take them to court.
