Anonymous is an anarchistic virtual community started around 2003. Though it was originally meant as entertainment, it had grown into a form of international hacktivism five years later, after a series of controversial, widely-publicized protests and hacking attacks on public domains.
Some of their biggest hacks include the Westboro Baptist Church, The Koch brothers, WikiLeaks' foes, and its recent campaign target has become the Church of Scientology due to hundreds of illegal actions, fraudulent activities, and human rights violations.
Anonymous protestors cover their faces with Guy Fawkes masks popularized by the comic book and film V for Vendetta in order to protect their identities and to preserve anonymity and to ensure their safety.
Though I agree with the idea of peaceful and legal protests against corporate greed and corruption, I fail to understand the call to action I read about in a story this morning while surfing my favorite conspiracy website by someone claiming to be part of ‘Anonymous’ requesting that everyone call in to local authorities on May 22nd (the day after the rapture according to 89 year old clergy Harold Camping) to report and thereby create the largest UFO hoax ever.
