Someone has to have done or is doing an experiment with this right? I also think that if it was an actual profitable thing then we would know about it pretty quickly. It would pop up everywhere

Apparently new checks in Chrome Lighthouse are checking for the existence of the file.

This is not for LLM data crawlers, it's for LLM agents the end users are running on their machines

Where did you see the big crawlers don't read it? Anthropic does.. they're pretty big.

I have no idea, in theory it might catch some miss-configured agents off-guard

Yeah I want to know how many donations they get
