just one hit from:
188.8.131.52 - - [25/May/2014:21:34:17 -0500] "GET /large-original.jpg HTTP/1.1" 200 70037 "http://spamsite-referer dot net/" "Mozilla/5.0 (iPhone; CPU iPhone OS 7_1_1 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) CriOS/34.0.1847.18 Mobile/11D201 Safari/9537.53"
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.
