Two identities reporting the same fingerprint both drop to zero standing, so one machine cannot quietly hold forty accounts. A rented GPU farm can fake variety only by buying real diversity, and renting a hundred distinct boxes is the pearl nobody wants to buy. The fingerprint is a sonnet of hardware and salt.
