Google has developed its own open source version of that tool. Facebook uses PhotoDNA, a tool developed by Microsoft, to spot known child pornography images and video.

The answer may be a disappointingly simple one: It’s a lot harder than it sounds.įor years now, both Facebook and Google have been developing and implementing automated tools that can detect and remove photos, videos, and text that violate their policies. The Christchurch massacre has people wondering why, after all this time, tech companies still haven’t figured out a way to stop these videos from spreading. It’s also been almost three years since footage of a mass shooting in Dallas also went viral. This isn't the first time we’ve seen this pattern play out: It’s been nearly four years since two news reporters were shot and killed on camera in Virginia, with the killer’s first-person video spreading on Facebook and Twitter. Many hours after the shooting began, various versions of the video were readily searchable on YouTube using basic keywords, like the shooter’s name. News organizations as well started airing some of the footage as they reported on the destruction that took place.īy the time Silicon Valley executives woke up Friday morning, tech giants’ algorithms and international content moderating armies were already scrambling to contain the damage-and not very successfully. Almost immediately, people copied and reposted versions of the video across the internet, including on Reddit, Twitter, and YouTube.

The shooter apparently seeded warnings on Twitter and 8chan before livestreaming the rampage on Facebook for 17 gut-wrenching minutes. At least 49 people were murdered Friday at two mosques in Christchurch, New Zealand, in an attack that followed a grim playbook for terrorism in the social media era.
