Crawler spam prevention?

Hi,

Try to add the following snippet to Custom Rules under Firewall menu:

# Block referral spam
<IfModule mod_rewrite.c>
	RewriteCond %{HTTP_REFERER} (keywords-monitoring-your-success​.com|free-video-tool​.com) [NC]
	RewriteRule .* - [F]
</IfModule>

If you need to block more domains, just add them to the list, but do not forget to separate them with “|” and include them within round brackets.

Warning: if you add “spam.com” to the list, any domain that has “spam.com” in it will be blocked, for example: “how-to-prevent-spam.com” etc. I suggest to avoid adding too generic domain names to the list.

Cheers,
Česlav
