One of my websites was absolutely destroyed by Meta's AI bot: Meta-ExternalAgent https://developers.facebook.com/docs/sharing/webmasters/web-...

It seems a bit naive for some reason and doesn't do performance back-off the way I would expect from Google Bot. It just kept repeatedly requesting more and more until my server crashed, then it would back off for a minute and then request more again.

My solution was to add a Cloudflare rule to block requests from their User-Agent. I also added more nofollow rules to links and a robots.txt but those are just suggestions and some bots seem to ignore them.

Cloudflare also has a feature to block known AI bots and even suspected AI bots: https://blog.cloudflare.com/declaring-your-aindependence-blo... As much as I dislike Cloudflare centralization, this was a super convenient feature.

I wonder if it would work to send Meta's legal department a notice that they are not permitted to access your website.

Would that make subsequent accesses be violations of the U.S.'s Computer Fraud and Abuse Act?

Crashing wasn't the intent. And scraping is legal, as I remember per Linkedin case.

If I make a physical robot and it runs someone over, I'm still liable, even though it was a delivery robot, not a running over people robot.

If a bot sends so many requests that a site completely collapses, the owner is liable, even though it was a scraping bot and not a denial of service bot.

The law doesn't work by analogy.
