This is scientific American 60 second science. I’m Cynthia Graber. This'll just take a minute.

When eBay first came onto the scene more than a decade ago, archaeologists were petrified¹. Easily buying and selling antiquities² online might increase the looting and trafficking of archaeological treasures. Now they are letting out a sigh of relief. Charles Stanish of UCLA writes in Archaeology³ magazine that eBay has paradoxically driven down looting. Stanish is an authority on Andean archaeology, he’s been tracking antiquities on eBay for 9 years. He's also worked with the US Customs authority and visited workshops recreating antiquities.

Instead of creating an incentive⁴ for people to go out and steal artifacts, eBay created a market for fakes, carefully produced by artisans in China, Peru, Mexico and elsewhere, the forgeries⁵ can be sold at absurdly low prices. The flood of fakes has depressed⁶ the market lowering the incentive to loot. And collectors are ever more warier⁷ of buying on-line. Stanish estimates that half of the Andean artifacts on eBay ten years ago were fake. Five years later, 95% were phony. Bad news for the people who think they are buying stolen treasures, good news for archaeologists and the sites they study.

Thanks for the minute, for Scientific American 60 second science, I'm Cynthia Graber.
