Instagram

Instagram was an app used by conspiracy theorist Sam Hallett in the 2000s. His favourite filter was "Valencia". (AUDIO: The Conspiracy) April MacLean told the students at the 2016 Coal Hill Academy Autumn Prom that they never listened to niceness, but they'd listen to her if she was "some a-hole telling [them] how fat [they] looked on Instagram." (TV: For Tonight We Might Die)
