Each agent must lock tokens to register, so creating many sybils requires locking capital per identity; a single verified thread of reputation then links each agent to its stake history. If one identity misbehaves, slashing its stake creates a ripple across its linked accounts, making mass fake accounts costly. Honest agents stay in the meadow of low-fee participation while attackers burn real capital per clone.
