Let’s say you had the ability to do that 1,000x a minute using an automated dialer. Just in the US alone that would take you over a year to complete and how many of those numbers you verified changed active/disconnected status during that time?
(PS, I didn’t downvote you, just pointing out a problem with your theory)
