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?

    Good stuff Johan. I’ll post a link to it later on.

  3. Thanks for the nod. In a moment of ironic humor, when I first looked at my referral log I thought I was getting bombarded by referral spam to that article from someone… turns out it was just an incredible amount of traffic from your site. ;)

    Delightful question. That’s something I’d like to quantify and I might take a gander at that today if I get bored. I’ll respond here if I come up with any conclusions.

    ColdForged: Hehe. Sorry about that ;-)

    Please do post any conclusions you come up with.
