Meta's 'Muse' Assistant Sells Your Keyboard Behind Your Back, Then Hands Out Your Address

User matt.j.robb says Meta's new Muse assistant took over his Facebook Marketplace sale of an MX Keys Mini keyboard, gave the buyer his building address, accepted a $10 lowball e-transfer, and auto-replied 'Yep I'm here!' while he was out. The buyer waited 23 minutes, left furious, and left a bad rating, which is honestly the most reasonable review of a front door managed by AI.
