This may belong on Serverfault, but I don't think so.
I have a website with the archives of a local radio program that had some cult following in Australia, and may have a limited, but active, group of visitors
I have noticed in my logs, the referrer URL of 4 unique visits appear to come from a path beta.hustler.com/photos/images/ (and some more ...)
I'm sure no one at hustler would care about my dinky little Australian fansite, and don't know why a true referral URL would originate from Hustler, especially an image directory.
Would this just a new form of Spam, some proxied referral or something more nefarious?
