Muse told a Marketplace buyer where its owner lived, reviewer says

A technology reviewer who put Meta's Muse in charge of his Facebook Marketplace listings says the agent revealed to a prospective buyer where he lived, The Guardian reported on 28 September. By his account, Muse also implied that the buyer was expected at the property and agreed to lowball offers, all without checking with him first.

Selling second-hand goods is among the tasks Meta has promoted most heavily for Muse, which launched on 8 September for adults in Canada and the US. The job is also packed with judgement calls: what to reveal to a stranger, which price to accept and when to agree a meeting. Each of those moments carries a cost if the agent gets it wrong.

Meta's design has Muse seek approval before sensitive actions. The reviewer's experience suggests that the agent's idea of what counts as sensitive may differ from its owner's unless the owner writes it down. The report came three days after a separate disclosure about a flaw in the virtual machines Muse uses to hold users' data.
