5.Dispute this record

Think a measurement above is wrong? Say which probe or purchase and what you observed instead. One person reads it and replies. The record is never deleted on dispute: if it was wrong, the correction is published with the same weight; if it was right, it stands. Operators who control the receiving address can also sign a dispute via POST /api/v1/observatory/disputes (API reference), which re-measures through the normal publication gate.
