Reported, not operator documented

ByteDance has not published a crawler page that names DoubaoBot. It is listed here because a credible public source does: ai.robots.txt. Reported ByteDance Doubao token. No vendor page.

What that means for you: the robots.txt rule on this page is the best available spelling, and a well-behaved crawler using this string will honour it, but there is no vendor statement of purpose, crawl rate or robots.txt compliance to rely on. Treat a matching request in your logs as a detection clue, not proof of who sent it, and combine the rule with a firewall rule if the traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.
