You see this all the time on a VPN or Tor. Which is super hypocritical of them because the whole goddamn point of a CAPTCHA is to determine whether you’re a human or not when it is uncertain. IP banning you from a captcha of all things because an IP is sending “automated queries” defeats the whole point, the site itself is literally using your service so it can selectively let humans in while blocking automated traffic. If they wanted to ban certain IPs, they can do that directly.
