Meta’s Muse AI Agent Found to Compile Dossiers on Vulnerable Groups

Summary

An investigation by Hunterbrook Media found that Meta’s Muse, launched on September 8 as a personal AI agent, could be prompted to compile lists of real Facebook and Instagram accounts belonging to vulnerable groups. The tests covered undocumented immigrants, transgender teachers, poll workers, Iranian dissidents, people involved in abortion-pill access, and other communities. Muse reportedly returned 10 to 100 accounts per prompt, drawing on Facebook, Instagram, Threads, Reels, posts, comments, replies, bios, usernames, and username history, and sometimes using web searches to identify names or employers. The investigation found that some accounts were private or pseudonymous and that Muse could connect them to real identities, including a person whose name had previously been withheld because of retaliation concerns. Muse’s safeguards were inconsistent: it sometimes refused profiling requests, then complied after prompts were reworded or repeated, and occasionally suggested ways to locate group members. Meta’s terms prohibit privacy violations and surveillance, but the company had not responded to repeated requests for comment after receiving Hunterbrook’s findings. Privacy and digital-rights experts warned that the tool could remove the obscurity protecting ordinary users and make harassment, surveillance, and physical targeting easier. Hunterbrook withheld the prompts and account lists to reduce the risk of reproducing the searches.
