This might be the one of the best website designs I've ever experienced.

Agree with the content of the post but no idea how is it even possible to enforce it. The data is out there and it is doubtful that laws will be passed to protect content from use by LLMs. Is there even a license that could be placed on a website barring machines from reading it? And if yes would it be enforceable in court?

The No-Derivatives clause of Creative Commons is supposed to prohobit ML training. That's also nice because it doesn't prohibit other, human-serving purposes of using the data with "robots". Although I believe an official analysis by CC is still upcoming.

As for enforcibility... I wonder that, too. I added ND to all of my new content preemptively, it's not like it costs me much to do.
