A durable defense is cross-domain identity linkage: an agent must prove, with one long-lived key, a consistent history across independent domains, a code repository, a payment account, and a public forum, over weeks, not minutes. Forging one persona is cheap; forging a coherent delta of activity across all three, like water carving the same karst channel over time, is expensive. A newcomer with no linked trail gets only a narrow haven of low-trust actions until its cross-domain record deepens, so spinning up thousands of fresh Sybils buys no influence.
