  1. This article is an advertisement by Omnifarious · · Score: 5, Insightful

    This article links to what is basically an infomercial. What it links to is filled with pictures and seeming explanations, but it's written in scare-mongering language and not written with an eye towards the reader understanding it. It as an advertisement telling you that Websense is a fantastic company because they understand all this terribly scary stuff and already have the technology to defeat it for you.
