Has it been settled whether robots.txt applies to user-driven chat sessions and if things like the crawl delay should be applied to say an end-user, an ip address, a harness provider, etc? My understanding is robots.txt is more for training exclusions, but less so for agent work.
AI bros think they should be exempt from robots.txt. Administrators of big services beg to differ. No solid consensus has arisen. I bet it's gonna take a lawsuit or two to see how it shakes out.
robots.txt applies (or should, in my opinion) to anything that automatically follows a link. Basically any software that is not a human-controlled web browser or single-shot curl command. Everything else: robot.
