Block spam referer and subdomains from htaccess

Question

I'm blocking spam referer with this code. This works for simple-share-buttons.com, the problem is that I'm still receiving visits from sites like site22.simple-share-buttons.com. Is there any way I can block also the subdomain rather than adding them all in htaccess?

RewriteCond %{HTTP_REFERER} simple-share-buttons\.com [NC]
RewriteRule .* - [F]

Answer 1

You can try the following method

RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*simple-share-buttons\.com [NC]
RewriteRule .* - [F]

or

RewriteCond %{HTTP_REFERER} site22.simple-share-buttons.com [NC]
RewriteRule .* - [F]

if you still having traffic from specific domain. it is using your Google Analytics Code to recreate fake information and sending that directly to Google Analytics.

So you cannot do anything with {HTTP_REFERER} to stop it.

You can see more information about this subject here and how to solve it.
