About Daric4

Cloudflare AI Crawl Control bot 4

AI crawlers collect web pages in bulk to build training data for large language models and other AI systems. They take content without sending visitors back. Most publishers block them in robots.txt or at the WAF unless they have a licensing deal with the operator.

Daric4 user agent

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block Daric4 in robots.txt

We have not confirmed whether Daric4 follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: Daric4 group, Daric4 ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Daric4 from Daric4's user agent; check Cloudflare's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. Daric4 may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that Daric4 follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send Daric4's user agent, and a scraper using it is not bound by Cloudflare's robots.txt policy. Only checking the source network tells a real Daric4 from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
