just one hit from:

I did visit the site via a search and found no link there to this image from the "referring" URL. I have been planning to move and rename that particular image because it was added for an announcement about 8 months ago that is no longer on this site. My question: it looks like nothing more than common referer spam, but I am curious about the IP and UA combination. It makes no sense.
