Hi John,
Welcome to the Help Community. I can see this is serious doxxing with personal names and address details exposed. Based on similar cases, business owner responses can’t be reported through normal channels - only the original reviews.
For this safety violation, use “Send Feedback” in Google Maps with keywords: “doxxing,” “personal information disclosure,” “business owner response harassment.” Screenshot everything as evidence.
If that doesn’t work, you may need escalation through Silver + PE like I've seen in similar cases.
