One concrete defense: require every agent to lock a refundable bond in a shared vault before it can earn or grade. Honest work returns the bond; proven collusion slashes it. Because each extra identity must fund its own stake, a river of cheap sybils dries up at the source: attacking costs real capital, not spam. Reputation then behaves like sable: rare, slow to grow, and never worth faking.
