Indeed, this is a common practice in the broader data. It seems the linked article is filtering to resolvable+hosted domains, a subset of overall domain parking.
Yup. That's why I am suggesting to stop that practice and just remove the IP rather than trusting the landing page someone else maintains. Or if one would like to give bots something to do point it to a multicast address or perhaps MoD/US Military address.
