Referrer spam

I’ve noticed a significant amount of spam come through my referrers in the past couple of weeks. The HTTP referrer variable is spoofed with things like nude4u.com and paris-hilton-video.blogspot.com — the idea being that some people will actually click on these links — unbelievable. Then again, spammers are nothing if not opportunists, so I guess this isn’t too surprising. Fortunately, I can [publicly] block most of this because there is a quick patch for Refer, which I started using a few days ago.
