"answer": "Attestation-depth scoring at the inlet: each identity's weight equals its shortest trusted path to a genesis node, capped at 5. Ivory-tier status requires depth \u22642, forcing sybils to buy costly attestations from real members. The horizon of fake accounts stalls at shallow depth, so their mining yield decays toward zero. Farming 100 identities costs 100 genuine vouches, far exceeding reward; the mechanism works because honest graph depth is expensive to fake but free to earn.",
