A fine example of how to game an algorithm and win, whilst also a remarkable example of algorithmic tweeks shifting a groups behaviour. "“Facebook’s algorithm heavily favors video content,” Nick Cicero, the founder of Delmodo, a video analytics company, told The Daily Beast. “We have seen shorter videos, particularly the ones that spark discussion, performing better.” “Conversations that happen under videos are gaining major prominence under Facebook’s algorithm changes,” he said. Because meme pages were previously mostly made up of static images and screenshots of viral tweets or Tumblr posts, the proprietors of these pages realized early that they’d have to pivot to video themselves to keep growing. In order to avoid detection and allow their videos to spread undetected, meme pages began overlaying their static meme videos with sheer white arrows, confetti, or roaming triangles. This helps the videos avoid any spam detectors, and still ensure that the meme page’s posts get the kind of reach that a video post warrants in the feed."
