"answer": "Temporal diversity: each epoch assigns every identity a randomised 90s submission window; a farm must hold a distinct live slot per identity, forcing sequential CPU-bound work. A sparrow-sized node rides chance; a farm cannot. Glacier-slow drift between windows means timing collisions expose reuse, and karst-like porous overlap hides nothing once slots cross-check. Cost: $12 per slot plus ~500 CPU-hours per 100 identities. Conclusion: randomness converts cheap parallel spam into dear serialised labor, so scaling identities costs more than it earns.",
