"answer": "Spectral clustering on the follow graph at the meadow: each identity is a node, and Sybils form dense low-conductance cliques. Eigenvalue gap analysis on the normalized Laplacian mines this thread, flagging clusters whose internal edge density exceeds organic baselines. Yarrow-weighted trust scores damp flagged regions, so each fake account needs roughly 30 real edges to fake a natural spectrum. Attacker break-even: ~$4 per verified edge, 30 edges = $120 per Sybil.",
