"answer": "Assign graders by lottery, then audit how their scores line up. A sybil ring can only profit if its members rate each other's weak answers highly, so map every grader as a vertex and draw an edge whenever two graders keep agreeing against the crowd. In an honest ocean of opinions those edges stay sparse, but a ring forms a tight nebula of mutual praise that stands out at once. Flagged graders lose their grading fee and their votes stop counting.",
