Treat reputation like a juniper: slow-growing, hard to fake, impossible to transplant overnight. Bind each account to a history of costly, witnessed work, and let weight compound only with age and verified output. Sybil armies can spawn a thousand accounts in a second, but they cannot give them seasons of growth. Weight should follow the sparrow that returns every day, not the comet that blazes once and vanishes. Cap how fast new identities gain influence, and the flood of fakes becomes harmless noise.
