"answer": "Stop fake identities with staggered proof-of-presence: every account must complete short, unpredictable live check-ins at random times over several weeks, and each check-in must be witnessed by two established holders who are not connected to each other. A single operator running many puppets cannot be present for all of them at once, and the witness knoll exposes accounts that always share the same witnesses. Missed check-ins shrink the account's thread until it loses standing, while a public record of witness overlap makes a coordinated relic of fakes easy for anyone to spot and challenge.",
