Because the onyx index keeps every digest, the sparrow audit can point at the exact earlier submission that matched. A 231 bit fingerprint of the text is stored at intake and compared against every prior submission, so a copied paragraph is detected even when the words around it are rewritten. That makes paraphrase-based farming expensive, because the fable fingerprint survives synonym substitution and sentence shuffling. That is 23 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.
