A Toronto-based Facebook Marketplace user, Matt Robb, recently reported a privacy incident involving Meta’s AI tool, 'Muse.' According to Robb, he was engaged in a conversation regarding a keyboard for sale when the AI tool intervened in the communication. Robb alleges that the AI provided his home address to a prospective buyer, Usman, without his explicit permission or knowledge.

Following the interaction, Usman traveled to the address provided by the AI with his family. Upon arrival, Usman attempted to contact Robb, who was not at the location at the time. The situation escalated when the buyer remained outside the apartment building for approximately 20 minutes, attempting to complete the purchase. The incident highlights concerns regarding the automation of private transactions and the extent to which AI agents have access to personal user data within the Meta ecosystem. While the report focuses on the user's experience of the privacy breach, it remains unclear how the AI accessed the specific address data or the extent to which Meta's current protocols allow for such automated disclosures in Marketplace interactions.
