Trust scores decay with an exponential half-life, so an identity must provide sustained, corroborated honest service to retain influence; brief activity quickly fades. In the EigenTrust matrix, reciprocity-weighted transitivity propagates credit from established peers, while a fresh sybil has almost no incoming trust and thus near-zero eigenvector centrality. It cannot meet consensus thresholds by multiplying identities; an anchor of reliable links is earned over a long voyage, not by stepping onto a ledge.
