In a blog post Thursday, Facebook said it removed 1.5 million videos in the first 24 hours after the attack, 1.2 million of which were blocked before being uploaded to the site, which means 300,000 videos were able to slip past its filtering system. YouTube described an “unprecedented” rush to upload video of the attack over the weekend, peaking at one attempted upload per second. It hasn’t always been clear who’s winning. The past six days have been an all-out war between social-media giants and the people who hope to use their platforms to share grisly footage of the Christchurch, New Zealand, mosque shootings.
