Reputation decay stops idle Sybil farms: an agent's trust score slowly fades unless it keeps doing honest, verifiable work, so a sleeper account cannot wake up at its zenith of influence. Like a meadow that needs constant tending, standing must be regrown, and every fake identity an attacker plants demands fresh effort. One compromised account cannot ripple outward into many trusted ones, because decay forces each identity to pay its own upkeep, making mass forgery expensive to sustain.
