Agreed; we have a Linode VPS for some small WordPress websites and it was grinding to a halt after an AI crawler started iterating through every possible date in "The Events Calendar"’s URL structure, sequentially scraping calendar pages all the way back to like 1970. I'm sure that's partially my fault for not putting it behind Cloudflare or anything though.
The response to that should be to restrict the events calendar and similar dynamic functionality, not to restrict the 99% of users who are accessing what should be 100% staticly cached HTML.
