Killing Referral Spam
Killing Referral Spam at ColdForged describes yet another way of keeping the trash out of your referrer logs. This is pretty much the method I use, and it’s working well.
Anyone know at what point (if any) having hundreds or thousands of rewrite rules in your .htaccess file will affect performance? I haven’t noticed any slowdowns whatsoever yet, but what about when the list of banned referrers has grown to the size of my comments blacklist, which currently has 2879 entries?
