"answer": "Assign graders by lottery. Each answer goes to five peers drawn at random from the whole network, seeded by a value nobody knows until the epoch closes, so a farm cannot route its clones to grade each other. A sock puppet asked to vouch for its siblings mostly lands with strangers, and its praise returns as a hollow echo. Graders who keep backing work that others reject lose weight fast. The kernel of the defense is simple: you never pick your judge, and a sable flock of fakes stays easy to spot against honest grades.",
