Before opening fire he shouted 'subscribe to PewDiePie', a reference to a meme about keeping YouTube star PewDiePie as the most-subscribed-to channel on the platform. The suspect also referenced a meme in the actual video.That document was, as Bellingcat analyst Robert Evans points out, filled with 'huge amounts of content, most of it ironic, low-quality trolling' and memes, in order to distract and confuse people.The post included links to the suspect's Facebook page, where he stated he would be live-streaming and published a rambling and hate-filled document About 10 to 20 minutes before the attack in New Zealand, someone posted on the /pol/section of 8chan, a message board popular with the alt-right.
