Given CloudFlare's direction, I won't be surprised if they start offering "anti adblock as a service" soon. Detecting it is still rather simple, and add in some punishments such as temporary IP blocking, and it would be rather effective.

(Note that everything CloudFlare talked about in this blog post also applies to adblock users, not just AI agents.)

The golden age of the Internet is not where people do it for money, or for views. That way lies clickbait and content farms. The golden age of the Internet is one where people share information because they want to.
