How to block CensysInspect
CensysInspect does not read robots.txt, so a polite sign is wasted on it. Refuse it at your web server or firewall instead. User agents are easy to fake, so pair this with rate limiting.
# robots.txt will not stop CensysInspect. Block it at the server.
# nginx
if ($http_user_agent ~* "CensysInspect") {
return 403;
}The same thing on Apache:
# Apache (.htaccess)
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} CensysInspect [NC]
