Facebook already prohibits people from offering marijuana, pharmaceuticals and illegal drugs for sale, and the company said on Friday that it was updating its policy to include guns. The ban applies to private, person-to-person sales of guns. Licensed gun dealers and gun clubs can still maintain Facebook pages and post on Instagram.
Although Facebook was not directly involved in gun sales, it has served as a forum for gun sales to be negotiated, without people having to undergo background checks. The social network, with 1.6 billion monthly visitors, had become one of the world’s largest marketplaces for guns and was increasingly evolving into an e-commerce site where it could facilitate transactions of goods.
