Facebook is cracking down on gun-related posts.
The social media giant is blocking minors from seeing postings of gun sales and will take down sales that don't require a background check or cross state lines.
The change is a win for groups like Moms Demand Action for Gun Sense in America and Mayors Against Illegal Guns, which have been lobbying for more restrictive gun policies at businesses like Starbucks, Staples and now Facebook.
"On the same site that people are sharing birthday parties and family reunions, there are photos of AK-47s," says John Feinblatt, chairman of Mayors Against Illegal Guns. "This is not in the bowels of Facebook. This is upfront, center and easy to access."
Until now, Facebook regulated only paid ads and sponsored stories, which could not promote weapons of any kind. Images of weapons are generally acceptable as long as the weapon is not pointed directly at the viewer. User posts could say almost anything.
The changes will extend to Instagram were someone searching for a hashtag related to gun sales will get a content advisory.
Moms Demand Action and Mayors Against Illegal Guns posted a petition on Change.org proclaiming "It's a social media gun show that we can't allow to go on any longer." By Wednesday morning, it had more than 90,000 signatures.
Facebook gun traders responded with their own petition saying "It's not ok to target only firearm enthusiasts for excessively restrictive rules." It has more than 8,900 signatures.
Similar petitions are circulating on a Facebook page called Guns For Sale that has more than 200,000 likes and thousand of posts from buyers and sellers. One, titled "Facebook: stay fair -- don't cave in to the anti-gun demands!" was posted by Stanton McCandlish, 45, of Oakland, Calif.
"There is no smoking gun here of big groups of Facebook users doing something wrong that requires some regulation," says McCandlish. "But Facebook is a private company, I guess if they want to have restrictive policies that alienate users, they can do that."
Recent news stories have fueled the fire. When a 15-year-old boy was caught with a 9 mm handgun at school in Kentucky, he told investigators he had arranged the purchase through the "Portsmouth Pickers" Facebook group.
"It's not just giving criminals access to guns, it's giving our children access to guns," says Shannon Watts, Founder of Moms Demand Action.
