The problem is that by the time the victim has fought to have their video re-monetised or reinstated, it's "old". You have a very short time to make money on videos these days. Yes there's rare videos that gain longer term success or get dug up and go viral, but for the most part those first couple days are vital.

I'm not sure. I thought companies uploaded their work and then the claims were basically automated. But admittedly I don't have experience in this area.

Regardless, we need to start seeing punishment for false claims. Under DMCA, wrongful claims could result in the claimants being charged with perjury, but obviously nobody is enforcing this part of it.
