Open PeopleLooker's opt-out form and search for yourself
Open peoplelooker.com/app/optout/search. The page is titled "Looking To Opt-Out of Our People Search?". Enter your first and last name, pick your state (or leave it on All), pass the Cloudflare check, and hit Search.
Note the link at the foot of the page: "Looking To Opt-Out of Our Property Search". That is a second, separate opt-out with its own suppression list. If you own property, run it too after finishing this one.
