It’s not that easy to steer clear of. I’ve bought a couple of books on other topics from Amazon and realized when they arrived that they weren’t worth the cost of the paper they were printed on. It’s easy enough to notice it’s bullshit, it’s harder to avoid spending money and time on them in the first place.
What content did they link that you have a problem with? It’s not the OP that linked that encyclopedia link that I won’t click on.
