Outsourcing the Right to Deletion
How does your personal data end up with businesses with whom you haven't interacted? It could be that data brokers might have sold your personal data to them. Data brokers collect personal data and sell it to other businesses.
In order to control your personal data, you could try contacting the various data brokers. But, there are a lot of them. Instead, you might hire a business to do that for you. A recent entrant is Incogni. It seems like a good paid service. If you are concerned about your personal data, you might want to consider such a service.
I have no affiliation with Incogni.
