I'm seriously confused about all this, also the allegations about her "witchcraft" are so over-the-top heinous and horrible it sounds more like a pizza-gate tier conspiracy than reality to me.
I don't think any of her work itself has any magical powers or anything. It's just that obscenely rich and powerful people are bored people, they want to do things that are considered taboo, so they pay a woman who says she'll make them a giant pentagram in goats blood and fashion a statue of Moloch in gold. And they go "whoa thats so out there!" "You can't just do that!"
Think of an edgy 14 year old but with billions and billions of dollars who wants to pay someone to do edgy things.
