The top-ranking HTML editor on Google is an SEO scam

What I don't understand is why does Google continue to use metrics that are so easy to fake and game.

Surely some kind of fairly trivial NN/Not very deep learning system can classify HTML content so that out of context links (like "Learn how to solve a Rubic Cube" in a Seventh Day Adventists sabbath lesson) and content that is copied is ignored or marked down.

Whilst I'm sure GPT-3 could be used to create more realistic looking fake content - this would eliminate 99% of the script kiddies creating low value SEO spamming sites.

Are non-sequiturs always malicious? For example, suppose you have a news site, and it has a story about Ukraine, followed by a story about school shootings. Even if two links next to one another are unrelated, that doesn't prove that they're not genuine.
