QAnon
A person identifying as "Q Clearance Patriot" first appeared on the /pol/ board of 4chan on October 28, 2017, posting messages in a thread entitled "Calm Before the Storm", which was a reference to Trump's cryptic description of a gathering of military leaders as "the calm before the storm". The poster later moved to 8chan, citing alleged security concerns.
The handle implied that the anonymous poster held Q clearance, a United States Department of Energy security clearance with access to classified information.[1]
