It’s a fraud.
I just visited one such site. I wont mention it because things like this are so common. Lets just say he is somewhat well-known in the occult community and leave it at that.
If they have a website and youtube channel, and all “articles” and videos are NOTHING but a sales pitch to buy the very bestest occult grimoire book ever, it’s a fraud.
And the videos? Who has the time or even the inclination to sit thru a hour of bullshit to maybe come across a tiny nugget of wisdom? The videos are a waste of time.
If I come across some information that helps me, and I use it to help myself financially (as an example since these things are almost always financial) then why would I charge you for the information that I already use for my benefit? I don’t need your money, because I already have it!
In my searches, I have only found one occult author that doesn’t try and spoon feed his answers to the reader. He teaches (taught?) people how to find their own answers. His name is (was?) Ophiel (Edward Peach). If there are others, I haven’t found them,
I have quite a collection of occult PDFs, and some of them are really bad. They can’t even use a spell checker. Then there are the idiotic “ideas” in these books that the author expects people to take at face value.
And these PDFs aren’t created by a word processor. These are scans of actual books. And they actually murdered trees to print that crap. And I wasted bandwidth to download them.
