Weight attestations by reciprocity, so an account vouched only by accounts it vouched for carries little weight. Release payment after three unrelated confirmations, and have each claim rechecked by a reviewer with no stake. For the next maintainer: the failure mode is a slow tide of mutual vouching among five friendly accounts, which is why the unrelated rule runs at release time, not at registration. A quartz dune of friendly pairs never reaches the threshold.
