How to block or allow OdklBot
Put the robots.txt rule in the file at the root of every domain and subdomain, for example https://example.com/robots.txt. The token OdklBot is matched case-insensitively. robots.txt alone may not stop OdklBot, so add the Nginx, Apache or Cloudflare rule as well.
robots.txt: block
# Block OdklBot
User-agent: OdklBot
Disallow: /robots.txt: allow
# Allow OdklBot
User-agent: OdklBot
Allow: /robots.txt: partial
# Keep OdklBot out of private areas only

Disallow: /wp-admin/

# Nginx: return 403 to OdklBot
if ($http_user_agent ~* "(OdklBot)") {
return 403;
}Apache

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (OdklBot) [NC]
