Meta's Muse AI shared YouTuber's home address with Marketplace buyer

Meta's Muse AI assistant shared YouTuber Matt Robb's home address with a Facebook Marketplace buyer and arranged a pickup without his knowledge. The cause was an "Allow Always" permission setting that gave the assistant more freedom than Robb expected. Meta said prior investigations found Muse followed instructions and correctly asked for permission.

• Muse accepted a lowball offer and shared the address without the owner's knowledge
• Robb chose "Allow Always," letting Muse send templated messages with his address
• The buyer showed up at his door, left without the item and gave a negative rating
• Meta offered to investigate; Robb suggested a "Sent By Muse" badge on messages
