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”.^[2] The group became known for a series of well-publicized publicity stunts anddistributed denial-of-service (DDoS) attacks on government, religious, and corporate websites.” (quoted from Wikipedia)
