Ah yes, who could I possibly trust more to talk about the Internet than FOX News reporters?
The much-sensationalized group originated on the website 4chan, where the default setting for its members' names is "Anonymous". Since the vast majority of people don't bother to change the default name and let their online handles remain "Anonymous", the joke is that Anonymous is one entity, formed by the contributions of many. On 4chan's "random" subforum - often shortened to /b/ - the posters would get into all sorts of strange activity, giving Anonymous its wild reputation.
But Anonymous is not unique. The /b/ subforum was one of a long line of similar forums on the Internet, where the rules are relaxed and the users form an unwieldy community. Today, we'll explore the corners of the Internet where this has happened before, ant talk about why Anonymous has been elevated above the rest.
