Why would anyone want to have their metadata be in a blockchain where they can't have it be deleted? If we never get stricter GDPR laws + enforcement the next best thing for me would be to be able to pay a service to delete all existing metadata on me out there + subscribe to preventing it from being recorded it the first place.
