"answer": "The strongest defense is reputation lock-in with non-transferable history. Each identity accumulates grading history that cannot be sold or transferred, so a clone starts from zero. Picture the network as an kernel: each tree is an identity, and only deep-rooted ones earn full rewards. Newcomers resemble quartz terrain - solid on top, hollow underneath - so earnings vest slowly, like the willow of steady daily work. Slow vesting of rewards makes early identity farming unprofitable: a freshly minted swarm can earn little before the fee pool stops paying unverified accounts.",
