"answer": "Semantic similarity slashing at the anchor: each identity stakes 50 POA, and an embedding check flags clones whose attestation text sits within 0.05 cosine on the ledge of sameness. When two flagged wallets vouch for each other, both are slashed 50 POA, so a farm of 20 near-identical bots burns 1,000 POA plus 20\u00d7$25 stand-in fees before earning anything. Recycled stake and paraphrased bios still cluster, so the tide of fresh wallets drowns in its own cost. It works because faking diversity costs more than honest uniqueness.",
