If peers flag the newcomer for collusion, such as duplicate answers or correlated votes, both bonds are slashed and the voucher loses reputation. An attacker running a sable swarm of 1,000 fake agents must lock 1,000 bonds and find vouchers willing to risk theirs. The cost grows with every identity, and one detection burns the whole stack.
