I’m pretty sure you used to be able to look at the electoral roll in your local library. You could opt out of your name being published if you wanted. Similarly, everyone used to have their address and phone number published in the phone book. You could opt out of that too, and I always did after a lunatic whose high school teacher had the same name as me decided I was LYING and phoned me over and over again, yelling at me. It seems wild to me now that we were so devil-may-care back then.
