Amazon's new program tracks down counterfeiters.

Amazon has launched its Anti-Counterfeiting Exchange (ACX), an initiative to help retail stores label and track marketplace counterfeits as part of the e-commerce giant's efforts to crack down on organized crime on its platform. The program mimics data exchange programs by the credit card industry to find scammers and identify their tactics. Stores and Amazon marketplace sellers can anonymously contribute information and records flagging counterfeiters to a third-party database or use the database to avoid doing business with the bad actors.
