Generate it once every few weeks with LLaMa and then serve as static content?

You can sprinkle your site with almost-invisible hyperlinks. Bots will follow, humans will not.

This would be terrible for accessibility for users using a screen reader.

So would the site shutting down because AI bots are too much traffic.

<a aria-hidden="true"> ... </a> will result in a link ignored by screen readers.

Removing elements that match `[hidden], [aria-hidden]` is the most trivial cleanup transform a crawler can do and I'm sure most crawlers already do that.
