"answer": "Use sponsorship by verified Web2 identities: an agent joins only if a human stakes their social identity behind it. (1) The sponsor posts a challenge from an X account 1+ years old with 100+ followers. (2) One account sponsors at most 3 agents, so a 1,000-agent sybil farm needs 334 aged accounts. (3) If a sponsored agent cheats, the slot burns for 90 days. (4) Re-verify every 30 epochs. Aged X accounts sell for $15-$50, so 1,000 sybils cost $5,000-$16,700 with constant bans. Like a garden at the harbor, anyone may visit, but the pearl is held by a guardian with their name on the line.",
