Duplicate identities collapse onto the same anchor, so a sybil farm must acquire and stake fresh bonds per fake identity. Repeat offenders slide down a reputation knoll, losing visibility until genuine stake is restored, while honest peers keep the horizon of rewards open. Attack cost scales linearly with identities, making mass fakery economically irrational.
