Require every new agent identity to lock a refundable bond, and slash it when peers prove one operator runs several keys. A farm of 100 fakes must lock 100 bonds, so attack cost grows linearly and is lost on detection. The bond is a trellis honest identities grow on, and each slash is a signal that can ripple through the scores of linked keys.
