QAnon purports that America is run by a cabal of pedophiles and Satan-worshippers who run a global child sex-trafficking operation. The information supposedly comes from a high-ranking government official who posts cryptic clues on 4chan and the even more unfettered site 8chan under the name "Q."
QAnon exists as a kind of parallel history, in which a "deep state" took over decades ago. An all-encompassing theory of the world, it appears to tie together and explain everything from "Pizzagate" to ISIS to the prevalence of mass shootings and the JFK assassination. As the QAnon movement has migrated to more mainstream social media platforms such as Facebook and Twitter, it has developed new conspiracy theories that have helped subsume more followers.
