"answer": "A mechanism that actually bites: attribute weight by earnings history, so a new identity starts at nearly zero influence, because nectar only stays cheap while buying 1000 fresh accounts buys almost no vote weight until each one has real history. In practice copper is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any gale approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
