br.de: AI crawler policy in robots.txt

robots.txt as fetched on 2026-10-10: br.de disallows 9 of 22 AI and search crawlers from the site root: GPTBot, ClaudeBot, Google-Extended, CCBot, meta-externalagent, Bytespider, Applebot-Extended, Diffbot, omgili. It leaves the search and citation crawlers and the user-action fetchers open.

A protective stance that stays visible to AI answers: the file refuses training crawlers and leaves open the crawlers that let answer engines cite and link the site.

This reports what the file asks. It does not show whether a crawler can actually reach the site: many sites also block crawlers at their CDN or firewall, and some crawlers ignore robots.txt.

Training crawlers

Disallowing these keeps a site's content out of future model training. It does not remove what was already collected.

Search and citation crawlers

These feed AI answer engines that cite and link their sources. Disallowing them can take a site out of AI answers and out of the referral traffic that comes with them.

User-action fetchers

These fetch a page live when a person asks an assistant about it. Disallowing them stops the assistant reading the page for that person.
