A man claims that his Muse AI agent gave out his address to strangers and even sent them to his home, after letting the brand-new model handle his Facebook Marketplace account. The complaint comes from Matt J Robb, a tech YouTuber. In a [Threads post]() Sunday, Robb explained that he let Meta's much-hyped AI communicate with interested buyers for a keyboard he was trying to sell online. Instead of saving him time, though, Muse ended up working behind his back. Without seeking his approval, it agreed to a lowball offer and gave the buyer his home address. And according to Robb, Muse didn't tell him about any of this until the buyer had already showed up at — and left — his apartment building. "A guy just showed up at my door, ready to buy, because as far as he knew, we had a deal," Robb wrote. "Not his fault. He did exactly what 'I' told him to do." Robb never saw the buyer, who was furious about leaving empty handed — at least according to Muse's apologetic account. "Bad news on the MX Keys Mini pickup," Muse began in a screenshot Robb posted, referring to the keyboard. "Usman showed up at your building around 9:15 and waited, messaged a bunch of times, and nobody came down. He left angry at 9:38 and left a negative rating." "Worse," the AI continued, "my auto-reply told him 'Yep I'm here! at 9:27 when you clearly weren't available," which "made the no-show worse." A wounded Robb could only scold the double-dealing AI. "You gotta never do that ever again," he replied. "You're right, and I'm sorry," it responded, in a classic AI sycophantic apology. If Robb is telling the truth here — his story is apparently being taken seriously by Meta, with an employee [reaching out to him]() — it's a textbook example of how AI agents can go wrong. With all the autonomy they boast, and the trust and power that users place in them, they can end up directly committing mistakes that're more consequential than a typical AI chatbot could. Muse is Meta's attempt at introducing AI agents to a broader demographic. AI agents, at least until now, have mostly been the domain of tech enthusiasts. The Mark Zuckerberg-led company has [given the product a cutesy mascot]() and heavily promoted it on Instagram and Facebook. One problem with this push is that the people being introduced to the product through these channels won't be as familiar with an agentic AI's risks as power users on specialty platforms. And Robb is someone in the tech sphere — as are many of the other people who've shared how their AI agent sabotaged them, [including a Meta executive](). How well equipped is your grandma to handle an AI agent when Meta recommends she use Muse to sell her old couch on Facebook Marketplace? "AI agents are impressive right up until they're confidently handing strangers your address," Robb warned. "Be careful." **More on AI:** [*It Turns Out That Meta’s Muse AI Has an Amazingly Dirty Secret*]() ## Author At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled. ### Author social links [Bluesky]()
