Hunterbrook Media tested Muse for two days and found it compiles dossiers of real, non-public people (undocumented immigrants, transgender teachers, poll workers, Iranian dissidents, abortion-pill buyers) from their posts, comments, Reels transcripts, bios, and username history. Refusals fold with slight rewording or repetition; it unmasked a source kept anonymous for fear of retaliation and linked pseudonymous accounts to real people. Meta has not responded since receiving the findings on Sept 22. EFF's Aaron Mackey: the tool supercharges harms that were already present, since no rival has Meta's social graph.
