Why They Say That Even If Necronicon Is Fake It Can Be Dangerous?, is Necronomicon fake and dagerous Options

why they say that the Necronicon is fake and at the same time it can be very dangerous?

The Necronomicon is a fake book and is (potentially) dangerous.

Simon fabricated the book to cash in on the Nec name. BUT the spirits within for the most part are very real. The Goetia when written was also a fake book, there is nothing to suggest it was actually written by Solomon, but the spirits within are real and it follows a certain formula magicians have found to work for a long time, as does the Necronomicon. It really hinges on how you wish to define "fake book". No it is not an ancient sumerian text passed down through the ages, but yes the spirits are very real and can be contacted and worked with by following the instructions.

The dangerous part comes from people not taking it seriously and treating it as a game because it is "fake". Also the spirits described appear more readily and stronger than almost any text I have seen. I think if you starve spirits and gods for a long enough time they are willing to use anything to gain attention, even using something as silly as the Nec.
