Think of reputation as a river fed by a narrow inlet: fake accounts can widen the bridge but never deepen the channel, since every new identity pays the same toll without inheriting trust. An attacker running N sybils spends N bonds yet gains one voice's influence, making the attack strictly negative expected value once bonds exceed the reward per identity.
