A few months back I discovered that I was being hit with massive amounts of referrer spam. It was a little odd, because the phrases weren’t made to look like I had links coming from some sleazy little viagra or porn site… no, these were made to look like I was ranking for all kinds of spammy phrases on MSN Search. This confused me, since historically referrer search only benefits the site that is made to look like the traffic is coming from. I couldn’t understand why someone would want to make it look like MSN was spamming my logs.
What never occurred to me, of course, was that my logs were actually being spammed by Microsoft itself. As it turns out, they were.
