On sites like YouTube this is what would happen:

Abusive bot makes fraudulent DMCA requests against your account. Your bot automatically files disputes. Abusive bot automatically verifies with youtube that they are the owners of the content, because they say so. Your account is demonetized and/or shut down for multiple dispute violations.

The entire system is rigged so the abusive bots have more or less free reign as long as they're backed up by some big media cartel. Google really doesn't want to anger said cartels who have been more than willing to sue individual people for trillions of dollars for sharing a single CD. Google has never been sued by creators for letting media cartels steal their works. They have no incentive to change policy at the moment.
