This seems to be a new shakedown racket of a business. "Subscribe for our services, or be victim to our shoddy automated takedown notices". Not too dissimilar to online ID protection services, that simultaneously sell your information
That doesn't make much sense, at least in this particular case. ChainPartrol's website describes themselves as "Real-time Brand Protection for Leading Web3 Companies", so it's unlikely that youtube creators would subscribe to such a service. Maybe if they were issuing takedown request for other "Web3 Companies" this allegation would have some merit, but that's not what happened here.
