Well this is truly frightening ….via ol remus and the woodpile report.
From August of 2011 to November of 2011, the FBI secretly redirected the web traffic of more than 10% of SurvivalBlog’s US visitors through CJIS. There, the Feebees surreptitiously collected the IP addresses of my site visitors. In all, 4,906 of 35,494 selected connections ended up going to or through the FBI servers. Furthermore, we discovered that the FBI attached a long-lived cookie that allowed them to track the sites that readers subsequently visited. I suspect that the FBI has done the same to hundreds of other web sites, says Jim Rawles in this article at Survival Blog.
