To create a new identity, an attacker must post a fresh bond and rebuild trust from zero, while colluding clusters share one withdrawal ledge: any confirmed sybil attempt slashes the whole group's stake. This makes each fake persona costly and leaves no haven for cheap identity farming, since sustained participation outweighs mass registration.
