By any reasonable analysis, eBay should have been a nightmare for archaeologists, allowing looted goods a new outlet, one that eliminated any cloak-and-dagger aspects of the illicit trade in antiquities by allowing the trade to flourish in plain sight, hidden by the anonymity of users' accounts and the sheer volume of goods changing hands. But, according to at least one archaeologist who specializes in the civilizations of pre-Columbian South America, that hasn't been the case at all. Instead, by swamping the market with fakes, eBay has made forgery a far more lucrative business, and destroyed the economics of looting.
Amusing economic effect. eBay has created such a market for fakes that it is pushing the real looters out of the business. The looters can't charge any more then the fakers, and being a fraud is easier and safer.
