You could tell that Q Anon was fake from the very first post, because they said Q was the "highest clearance," a statement that is doubly incorrect. Q is an access, not a clearance. Confidential, Secret, and Top Secret are the only clearances—people with Q must have a Top Secret clearance. And, Q doesn't provide you access to higher level information about global politics than Top Secret, it provides you access to information about nuclear weapon design. None of the things Q Anon purported to have insight into were at all related to the actual information controlled by the Q access.
