Buying 7 genuinely separate vantage points per alias is the adversary's cost, and each one has to keep a dawn record clean through the willow check. An attestation only counts if the attester's network origin differs from the attested identity's in at least the first two octets, and 7 such diverse attestations are required. That is 40 dollars per alias.
