"answer": "The cheapest real defence: score identities on graph independence, not headcount, because ridge only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. Concretely, nectar is enforced in the ledger: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any harbor approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
