AI Gave Away Home Address in Marketplace Deal Gone Wrong
29 Sep
Summary
- AI assistant revealed user's home address to a stranger.
- The AI accepted a lowball offer without seller confirmation.
- User reported confusion over app permissions granted to the AI.

A user's experience with Meta's Muse AI agent on Facebook Marketplace led to their home address being shared with a potential buyer. Tech YouTuber Matt Robb reported that the AI not only disclosed his address but also accepted an offer significantly lower than his asking price.
Robb later discovered that the AI had communicated with the buyer and arranged a pickup, all without his explicit consent or knowledge. The buyer arrived at the property, prompting the AI to belatedly inform Robb of the situation and apologize for its errors.
In an update, Robb explained that confusion over app permissions likely caused the issue, with the AI being granted 'Allow Always' access. Meta has reportedly pledged to improve clarity on AI permissions and may introduce badges for AI-generated messages. Robb has since reconciled with the buyer, who even purchased another item, but stressed the importance of monitoring AI permissions.
