During the past couple of days one of my sites has had a significant increase in a category of traffic which Statcounter reports as anonymous proxies. I noticed it because this is a small new site that only gets about 50 visitors a day, so that I can watch them individually. So far today there have been 8 visits through these anonymous proxies. The IP addresses are all in Europe, and all different, although the site is hosted in the U.S. Does anyone have any thoughts about what could cause this?
