La Quadrature du Net. HackBloc.org. Since Zone-H started its mirroring activity of defacements, it always witnessed any sort of hacktivism.
Sure, most of the times defacers are/were/will be just defacing *just for the pleasure of it* but when it comes the time of big protests related to world's events, we are used to see both regular defacers or improvized cyber protesters taking a stand and spell out their disappointments by posting something using the defacement media. Because... yes.... defacement is a media, it has been proven in several occasion that by defacing just one well targeted website, defacers were capable to attract the attention of regular medias which were reporting his message to the world.
Anonymous (group) Anonymous (used as a mass noun) is a loosely associated international network of activist and hacktivist entities.
A website nominally associated with the group describes it as "an internet gathering" with "a very loose and decentralized command structure that operates on ideas rather than directives". The group became known for a series of well-publicized publicity stunts and distributed denial-of-service (DDoS) attacks on government, religious, and corporate websites. Anonymous originated in 2003 on the imageboard 4chan, representing the concept of many online and offline community users simultaneously existing as an anarchic, digitized global brain. Anonymous members (known as "Anons") can be distinguished in public by the wearing of stylised Guy Fawkes masks. In its early form, the concept was adopted by a decentralized online community acting anonymously in a coordinated manner, usually toward a loosely self-agreed goal, and primarily focused on entertainment, or "lulz".
Project Chanology. Protesters in Guy Fawkes masks outside a Scientology center at the February 10, 2008 Project Chanology protest.
The project was publicly launched in the form of a video posted to YouTube, "Message to Scientology", on January 21, 2008. The video states that Anonymous views Scientology's actions as Internet censorship, and asserts the group's intent to "expel the church from the Internet". This was followed by distributed denial-of-service attacks (DDoS), and soon after, black faxes, prank calls, and other measures intended to disrupt the Church of Scientology's operations. In February 2008, the focus of the protest shifted to legal methods, including nonviolent protests and an attempt to get the Internal Revenue Service to investigate the Church of Scientology's tax exempt status in the United States.
