Does Cloudflare's Disallow AI Training also block bots?
By Brightiny9Published
Yes. The robots.txt file only asks, but Training = Disallow with Bot Preference Sync also blocks training crawlers at the edge (checked 2026-11-02).
Yes, with Bot Preference Sync on. The robots.txt file only asks bots to stay out, but Cloudflare's docs say setting Training to Disallow also "enables edge blocking for AI training crawlers". Search crawlers that Cloudflare calls accountable stay allowed. Checked 2026-11-02.
| Item | The robots.txt file | Training = Disallow with Bot Preference Sync |
|---|---|---|
| Does it ask or enforce? | Asks. Compliance is voluntary | Asks and blocks training crawlers at the edge |
| Search crawlers | Not named in the list | Accountable mixed-use crawlers stay allowed for search |
| Plans | All plans | Cloudflare's blog says the new controls are available "on all plans". It does not say separately whether the edge blocking is |

Does the robots.txt file itself block anything?
No. Cloudflare's page says:
"robots.txt compliance is voluntary." (Cloudflare docs, updated 2026-10-22, checked 2026-11-02)
The same page says the file states your preferences but does not stop crawlers from reaching your content at a technical level. It lists eight bots: Amazonbot, Applebot-Extended, Bytespider, CCBot, ClaudeBot, Google-Extended, GPTBot and meta-externalagent.
What does Training = Disallow add?
The same docs page says that with Bot Preference Sync enabled:
"setting Training to Disallow adds managed directives and enables edge blocking for AI training crawlers." (Cloudflare docs, checked 2026-11-02)
Cloudflare's 2026-09-15 blog post fits that. It says the network can publish the preference and "block the ones that ignore it". It also says every other training crawler is blocked, including training-only crawlers run by Amazon, Anthropic, Meta and OpenAI (Cloudflare blog, 2026-09-15, checked 2026-11-02).
Does this clash with "use AI Crawl Control to enforce"?
It looks like it does. The same docs page also says: "To enforce access restrictions, use AI Crawl Control to block selected AI crawlers." (checked 2026-11-02). Our earlier article 19 relied on the page's wording that AI Crawl Control is the tool for enforcing blocks. The page does not explain how that fits with the "edge blocking" sentence above. Two readings are possible: the enforce sentence is about the file alone, and Bot Preference Sync adds blocking on top; or the page has not been fully updated. We could not tell which, because the page does not say. What we can say is that both sentences are on the same page, and the one about Disallow is the more specific. Neither page we read says where to see these blocks in your dashboard, so check your own settings and logs rather than trusting either sentence alone.
Which crawlers stay allowed?
The blog says accountable mixed-use crawlers remain allowed for search. In our earlier check, Disallow AI Training did not touch Googlebot.
Is part of our older comparison out of date?
Yes. The same blog post says Cloudflare will deprecate Managed Robots.txt in favor of Bot Preference Sync, and will deprecate the "Block AI Bots" setting (Cloudflare blog, 2026-09-15, checked 2026-11-02). Our article 19 compared those two settings with AI Crawl Control. Two of its three controls are being replaced. The blog gives no such notice for AI Crawl Control.
What does this change in our older articles?
Our article on Block AI bots vs managed robots.txt said the managed robots.txt setting only asks and does not enforce. That is true of the file alone. It was wrong for the setup that article describes: Training = Disallow with Bot Preference Sync also blocks. That was our error.
Our article on the managed bot list quotes the "voluntary" line too. Read it as being about the file.

| The edge blocking itself is available on every plan | Not stated separately | n/a | 2026-11-02 | Not confirmed |
| How "enforce with AI Crawl Control" fits with the edge blocking | Same docs page has both sentences | 2026-10-22 | 2026-11-02 | Not confirmed |

Our read: if you want training crawlers out without hiding from search, this setting does more than its robots.txt file suggests. Open your dashboard to see whether Training shows Disallow and Bot Preference Sync is on.
