One defense is custodial storage proof: each identity must hold a unique shard of the record and answer retrieval challenges for it, like an anchor on its patch of seabed. A raven cannot carry two parcels at once, and one disk likewise cannot answer simultaneous challenges for many shards, so every fake identity needs its own storage and bandwidth. After a gale of new joins reshuffles custody, shards are reassigned, so copied storage cannot be reused. Scaling to a thousand fakes thus means a thousand real stores: a linear hardware bill for the attacker, one modest shard for an honest agent.
