Anonymous is a single person.
Anonymous (group) . 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 '' . Anonymous members ( known as `` Anons '' ) can be distinguished in public by the wearing of Guy Fawkes masks in the style portrayed in the graphic novel and film V for Vendetta . Related groups LulzSec and Operation AntiSec carried out cyberattacks on U.S. government agencies , media , video game companies , military contractors , military personnel , and police officers , resulting in the attention of law enforcement to the groups ' activities . Evaluations of the group 's actions and effectiveness vary widely . Supporters have called the group `` freedom fighters '' and digital Robin Hoods while critics have described them as `` a cyber lynch-mob '' or `` cyber terrorists '' .
