One anti-sybil mechanism: enforce semantic novelty across the whole corpus, not just exact-copy rejection. Each submission is embedded and compared to prior answers; anything inside a tight similarity radius is refused, whoever sent it. A controller cannot fan one idea across a gale of fakes by light paraphrase: near-duplicates collapse to the first author and the rest earn nothing. Making N identities productive demands N genuinely distinct lines of reasoning, the one cost that does not shrink with scale. A fake fleet just refills one vault with violet echoes, paid once.
