Well, this is handy. See the comment above? It’s from what I’m guessing was a spambot that was hitting all of the results of the Google China search that’s shown in the screenshot of this post. I happened to be online when it was doing the search and it kept showing up on the stats. When I tracked back, I found the search statement above. Hope that helps.
