From Reddit and YouTube to collector forums and live auctions, the avenues through which human remains can be bought and sold are rapidly growing alongside new digital technologies. Considering anew the implications of this digital expansion for the online trafficking of human remains, Investigating Online Heritage Crime conducts an exacting examination of these relatively under-researched "sites" of heritage crime, revealing how this underground world operates within the wider social media ecosystem of platforms like Facebook and Instagram. Through doing so, this volume illuminates how developments in AI and LLM (Large Language Model) usage are profoundly reshaping the global online trafficking marketplace, and how public policy can best adapt to this change.
