The point is:

1. There are countless ways to hide machine-readable content on the blog that doesn't make a visible impact on the page as normally viewed by humans.

2. Even if you somehow verify what the LLM will see, you can't trivially predict how it will respond to what it sees there.

3. In particular, the LLM does not make a proper distinction between things that you told it to do, and things that it reads on the blog.
