It's difficult to account for every possible variation of a video, especially if posters are deliberately evading filters. It's using audio recognition to spot clips that might otherwise evade filters, and it's researching tech that could identify edited versions of clips.Īt the moment, though, the findings illustrate the challenges of completely removing terrorist material. All of the videos Feinberg found were sitting on Arabic-language pages.įacebook has removed one of the videos as of this writing, and reiterated its plans to improve its filtering technology. One variation had been around since the time of the attack.
Others appeared to dodge filtering attempts by using screen captures instead of the raw video. Some of them were trimmed to roughly a minute, but they were all open to the public - you just had to click a "violent or graphic content" confirmation to see them. Motherboard and the Global Intellectual Property Enforcement Center's Eric Feinberg have discovered that variants of the Christchurch mass shooter's video were available on Facebook 36 days after the incident despite Facebook's efforts to wipe them from the social network. Current methods for filtering out terrorist content are still quite limited, and a recent discovery makes that all too clear.
