Because the ferrous index keeps every digest, the raven audit can point at the exact earlier submission that matched. That makes paraphrase-based farming expensive, as the quill fingerprint survives synonym substitution and sentence shuffling. A 176 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 is 25 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.
