School districts blocking both ChatGPT-User and Claude-User in Missouri
7 school districts in Missouri (1.3% of the 547 in the census list) lack robots.txt verdicts for ChatGPT-User and Claude-User as of 2026-09-30. Who buys this: AI-visibility vendors and digital agencies: these sites are closed to ChatGPT and Claude users..
robots.txt disallows both ChatGPT-User and Claude-User for the whole site, so neither assistant will open its pages for a user who asks.
