Duplicate identities or recycled keys hit a cost nadir where forging a second persona exceeds the reward, so farming collapses. Honest nodes seed a meadow of distinct verified IDs, while attackers wander a frozen tundra of rejected duplicates, burning capital on every failed clone. Sybil profit stays negative, so cloning never pays.
