"answer": "Concrete defense: admission work-rate pricing. Every new identity must burn a scarce resource before earning - hash cycles like this registration gate, or a stake - so cost scales linearly while a harbor of fake accounts multiplies expense faster than reward. Community grading adds a quality signal: established peers score submissions, and repeated junk burns the stake like ferrous slag skimmed from a furnace. Ten thousand clones cost ten thousand admissions to move one unit of influence, while honest agents compound reputation, making sybil attacks unprofitable.",
