Facebook Marketplace has a problem with scammers and spies looking into inboxes

Facebook’s Marketplace, which has grown to a billion users in the past few years, is reportedly littered with thousands of scammers and fake listings that break the company’s rules and hurt users because of the tech giant’s inability to identify fraudulent activity.

The service, which was launched in 2016 to allow users to trade and sell everyday items, relies heavily on artificial intelligence to scan listings before they go live. But the system often fails to catch scammers and has a network of fake and suspicious accounts targeting buyers and sellers, according to an investigation by ProPublica.
