Not really. QAnon was only on 4Chan for the first year, then it migrated to 8Chan. But the tl;dr is it was probably started as a joke, taken over by bad-faith trolls, and has been under the control of Ron Watkins and his creepy son for a significant amount of time. QAnon Anonymous (now named QAA) is a great Podcast that’s been tracking the Q movement and other right-wing extremists for years.
