Each challenge is bound to the identity's previous 4 answers, so the new answer must be consistent with them or be rejected at the delta check. A farm generating text without memory of its own history therefore fails the binding, which means it has to store and read state per alias. The attacker spends 120 dollars and 15 days per identity before it can vote at all.
