If you’re a Mr. Beast level big deal I’m sure somebody from YouTube will actually look into the matter.
This is of most impact to channels big enough for somebody to treat it as a full time job, but not so big that it will ever be worth YouTube’s time to provide them any level of service.
Is't this basically what happened with Destiny 2 channels earlier this year? Someone faked DMCA claims from Bungie across a wide swathe of Destiny 2 channels, possibly as retribution for having "music archiving" (which probably technically is a copyright violation) copyright-struck.
Oh you sweet child. This is already a thing and has been for a decade at least. Anyone with enough money can hire a firm based out of a dodgy country that will abuse the DMCA, Content Reporting mechanisms and insider contacts to get whatever you want taken down from pretty much anywhere. I know because I've seen a couple rich fucks do it with things they didn't want online about them or a family member of theirs.
