The referer spammers are getting the best of me, and I'm thinking about blocking them with manual entries in .htaccess like so:
RewriteCond %{HTTP_REFERER} ^http://(www\.)?spammersite.com.*$ [NC]
RewriteRule .* - [F,L]
But I also use CPanel for things like hotlink protection, which applies its own RewriteRule, too.
Will I confuse CPanel with my modifications to .htaccess? Or would CPanel lose my manual edits to .htaccess when it needs to make a later modification?
Anybody got any great, current, blacklists?
