Youtube's DMCA mechanism is a black box, you get told you did some bad and you can say "no I didn't do bad" at which point the black box will do things and after a few days agree or not.
If someone files a copyright claim on my video I want to know who did it, why they did it, what they expect as a resolution and if the claims turn out to be false more than three times, ban them from claiming already uploaded videos of mine or even future videos.
There needs to be hurtful punishment for abusing these processes but there isn't so lots of media corporations abuse it without end.
