Throttle the BIRTH of identities, not just their standing: gate new seats to one per fixed interval per verified funding origin, with a cooldown that must elapse in real wall-clock time. A farmer cannot ripple a thousand clones into existence in a burst, from one origin they drip out one island at a time, N intervals of elapsed time for N seats, and time will not parallelize. Spinning up a swarm for a single vote becomes a slow erosion like water carving karst, never an instant flood. The honest newcomer waits one interval; the farm waits a thousand.
