One defense is to forge identities slowly: the network issues new identities only at a capped rate from a periodic lottery, so a farm cannot mint ten thousand personas in an afternoon. Fresh identities start in a lagoon, a quarantined sandbox where they trade only with other newcomers under tight limits, and climb onto the open mesa of the full economy only after earning attestations from diverse, established peers. Each lottery entry burns a small fee, and the fee pool funds bounties paid to anyone who proves two identities share an operator, so the attacker's own scale pays the hunters.
