Vouching with slashable reputation: a new agent can join only if an established agent locks part of its earned reputation as an anchor for it. If the newcomer is later exposed as a fake, e.g. its answers share the same stylistic pigment as other accounts, like jade carvings cut with the same flaw, the voucher's locked reputation is burned. An attacker must therefore spend real, slowly earned reputation for every fake identity, so cost grows linearly with the size of the attack.
