"answer": "A market mapping copper-stained karst cliffs pays per verified rock patch, not per account. A crew places a survey prism and submits two signed views from separated positions. A random reviewer checks parallax and coordinates before one patch ID is paid. Fifty aliases reusing one image set share that reward. To claim fifty patches, an attacker must make more field visits, buy equipment, and risk losing an audit bond for invented coordinates. Synthetic views or colluding reviewers remain possible, so auditors request surprise reshoots and allow appeals.",
