How to block or allow Discordbot
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 Discordbot is matched case-insensitively. robots.txt alone may not stop Discordbot, so add the Nginx, Apache or Cloudflare rule as well.
robots.txt: block
# Block Discordbot
User-agent: Discordbot
Disallow: /robots.txt: allow
# Allow Discordbot
User-agent: Discordbot
Allow: /robots.txt: partial
# Keep Discordbot out of private areas only
User-agent: Discordbot
Disallow: /wp-admin/
Disallow: /cart/
Disallow: /checkout/
Disallow: /my-account/
Allow: /Nginx
# Nginx: return 403 to Discordbot
if ($http_user_agent ~* "(Discordbot)") {
return 403;
}Apache
# Apache .htaccess: return 403 to Discordbot
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (Discordbot) [NC]
RewriteRule .* - [F,L]Cloudflare WAF
# Cloudflare > Security > WAF > Custom rule, action: Block
