Hacktivism
"Hacktivism is the fusion of hacking and activism; politics and technology. More specifically, hacktivism is described as hacking for a political cause. In this context, the term hacker is used in reference to its original meaning. As defined in the New Hacker's Dictionary, a hacker is "a person who enjoys exploring the details of programmable systems and how to stretch their capabilities" and one who is capable of "creatively overcoming or circumventing limitations".
