The same unique illegal-dumping photograph appears on Instagram, on Reddit, and in a Facebook group screenshot. What should cross-platform correlation seek?
Select an answer to reveal the explanation.
Short Explanation
The same dump-site picture on three networks is a relay race, and you want the first baton pass. Reverse image plus timestamps beat assuming the Facebook screenshot started it. Keep every copy; just rank them by time.
Full Explanation
Cross-posting can hide which public account first published a unique image. Reverse image search combined with capture timestamps recovers the path across Instagram, Reddit, and Facebook without treating a screenshot as automatic origin. Simultaneous or near-simultaneous posts do not prove an official city camera. Destroying copies destroys evidence; the product is a sourced path, not a single remaining file.
