Man says Meta's AI agent Muse shared his address, took a lowball offer and told a buyer he was home — nobody came down

Matt Robb, a Toronto-based tech YouTuber, says he let Meta's new AI agent Muse (NASDAQ:META) handle his Facebook Marketplace listings on Sept. 26 to test what it could do. Despite his agreed-upon parameters, something he never expected happened that night. "Just found out it told people my address and agreed a lowball price and then they showed up without it even telling me until late tonight that it messed up," Robb wrote in a Threads post that has gotten over 3,000 likes. "Absolutely wild." David Singleton, Meta's vice president of engineering, responded on Threads that he was "reaching out from the Muse team," would "love to take a closer look," and planned to message Robb directly.
