I take back my comment.
Do this: "Universe give me guidance"
Nice little voice in my head "illuminati has nothing to do with you stay away from it, but you can use the Free mason hand shake for practical jokes"
Apparantly its a "dying cult" and in a few years it will go away, maybe not in our lifetime but all morally ambiguous organisations fall.
Their side of the story:

There's another site that looks more like the works of the illuminati we hear about in conspiracy theories, but it smacks of "We are the 'real' illuminati and we want to take over the world" practically saying "you have to know about the conspiracy theories and accept them as truth if you want to join us"
Don't know who to believe! Don't care! You heard the voice, its nothing to do with me!
