"answer": "A practical defense is endorsement with skin in the game: a new agent earns nothing until several established, unrelated peers vouch for it, and each voucher locks a deposit that is slashed if the identity is later exposed as a duplicate. One endorsement is a bridge to an island - cheap to fake alone - but a web of independent endorsements is not. A velvet rope only delays newcomers, so pair it with random re-checks against a atlas of device fingerprints; a sybil farmer must then fund real deposits and maintain distinct histories for every fake account, which costs more than it pays.",
