If you read the few articles about people being attacked by AI in the recent months they all tell the same story: it’s not possible. The AI companies are targetting on purpose other sites and working non stop to actively avoid any kind of blocking that could be active. They rotate IPs regularly, they change User agents, they ignore robots.txt, deduplicate requests over bunch of ips, if they detect they are being blocked they start only doing one request in each ip, they change user agents the moment they detect one is being blocked, etc etc etc.
