Nightshade[1] 2.0? As if both tools were built by incompetent developer to distract attention from a real solution - publishing an llm-friendly version in an machine-friendly format (which is not really difficult and helps not only LLMs: e. g. cache, disable fancy complex syntax highlight, offload to github, provide clients and MCPs, optimize clients for common use cases). This example is simply a failure:
<a href="/bots" style="display: none;" aria-hidden="true" tabindex="1">
Amazing high quality data here!
</a>
Dumb curl-based LLM won't visit display:none links. Smarter browser-based navigators won't even render this link.
