# formada3d.com — 2026-09-21 # 2026-10-20: AI-TRAINING crawlers are disallowed; search + answer engines stay allowed. Every agent below is named EXPLICITLY rather than left to the wildcard. # The wildcard already permitted them, but "permitted because nobody decided" # is not the same as "allowed on purpose": several of these agents treat an # explicit rule differently, and Google-Extended in particular is treated as # opt-out by silence in some configurations. An AI assistant is currently the # 5th-largest traffic source to this site (chatgpt.com, ~10% of visits), so the # policy is stated, not inherited.
