Find your listing, then fill out the opt-out Google Form
Go to the opt-out form: docs.google.com/forms/d/e/1FAIpQLSe…/viewform. It's a Google Form titled "Contact information" with the prompt "To remove your info, please kindly provide the following info:"
Five fields are required, each marked with a red asterisk: First Name, Last Name, Your Email, URL (the listing you want removed) and a Removal Confirmation choice. Only the free-text message at the end is optional. Search the site for yourself and copy your listing's URL before you start. The form won't submit without it.
Google Forms requires you to be signed in to submit, and the header shows which account you're submitting as (with a "Switch account" link). The "Not shared" indicator means Google isn't attaching your account address automatically. It doesn't mean the form collects no email, because one of the required questions asks you to type one. Use an address you're willing to give this operator.
