After they achieve fame, many artists and celebrities get introduced to secret "elite" societies. It's pure exoteric new age LARPery for the most part, but a few do manage to display the acumen to achieve the higher esoteric degrees where they learn warped and twisted versions of Hermeticism and the Eleusinian Mysteries. This allows low level celebrities to be part of a super secret club where the real Cabal can easily manipulate them while keeping them under close watch. So symbols alone are relatively meaningless. Most often, the overuse of imagery already well known to the general public is usually the sign of low level "Illuminati" LARPers.
