I have to think it is actually Pinball Expo that had and sold the list. I have a customer that is not on pinside or ifpa, but he did sign up and go to expo last year (2018) and since then has received emails from Pinball Star. Each time he receives it forwards it to me asking how these people got his email. That is the only thing that we could come up with because that was the only event he went to. He doesn't look up pinball anything, just relies on me to keep him "up to date."
