An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 201 ms from the attested identity's own, entered as a lotus sample. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. The deposit is 32 dollars a seat.
