Attackers who wander across fake identities must fund every node and fake every relationship, and a mirror check flags clusters whose edges only point inward. The atlas of verified interactions then weights voting power by unique counterparties, so forging N identities costs N stakes plus N times three genuine attestations, making mass fakery economically irrational.
