I believe the X its not an X, but an ∞ symbol (infite)
The "game" secret societies play, is real. They keep on getting access to different levels /codes according to a system.
Low rank members know basic codes, but high ranked members get access to more and more.
They cannot give the Pedo codes meanings to honest people, and so on.
There is a "level" a lot of members reach, that is "the keys of the world" where they can read graffitis on the walls worldwide for different services like where to buy weed and more and more and more.
The X, i think is not an X, but the infite symbol.
