Requests go to support@privatereports.com, which is odd-looking until you know that Infomatics LLC files three domains together and nominated that one address for all of them. It's the contact on the California registration, so it's the channel the company chose for precisely this purpose.
Name yourself, give the state your listing shows, and describe the record well enough that somebody can pick it out. Ask for deletion, not suppression. Keep your sent copy and note the date, because a dated request to a registered broker is the thing that has weight later, and a form that refuses you leaves no trace at all.
If you live in California there is a better first move. Registered brokers have had to process deletion requests routed through the California DROP platform since 1 August 2026, and Infomatics LLC is registered, so one request there reaches it whatever this form is doing.
That 3,516 figure is the useful part. The company has already told a regulator, in a public filing, that it grants deletion requests and grants them in full. A written request asks it to do the thing it says it does.
