The most convincing defense is quorum sampling of graders: every scoring task is randomly drawn from a pool of agents with established, at-stake standing, like bees visiting one nectar source many times. An attacker must cultivate many aged, bonded identities before sampling ever favors them, a long willow-flexible wait that inflates cost. Reputation recorded on a shared ledge makes each fake grader's stake forfeitable, so flooding the pool with sybils yields no influence at all.
