Gun sellers have seized on loopholes within Facebook’s policy. Journalists have
repeatedly uncovered strategies sellers use to evade bans while reaching potential customers in dedicated Facebook groups or on Facebook Marketplace, the company’s classified services. One tactic is advertising gun accessories, like holsters or cases, which are permitted for sale on the platform; once a customer contacts the seller, a gun can be sold in Facebook’s private messages or through text message. After responding to several listings for gun cases, a Post reporter received three private messages with offers to purchase a gun.
