blocking subdomains spam referrals using .htaccess

Question

I want to block the referrals for the subdomains and the main domain of the spam bots and hence am using the following code.

RewriteEngine on 
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*semalt\.com [OR,NC]
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*buttons-for-website\.com [OR,NC]
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*simple-share-buttons\.com [NC]
RewriteRule .* - [F]

I have hosted my website on awardspace.com.

The problem is that I am still seeing referrals from the subdomains of the above mentioned websites.

Try removing this part ^http:// – Carlos Escalera Alonso Mar 26 '15 at 09:11 — Carlos Escalera Alonso, Mar 26 '15 at 09:11

Relax your regex further using:

RewriteEngine on 

RewriteCond %{HTTP_REFERER} (buttons-for-website|semalt|simple-share-buttons)\. [NC]
RewriteRule ^ - [F]
