SOCK PUPPET

Definitions of SOCK PUPPET

 a hand puppet made with a sock (una marioneta hecha con un calcetín)

Or, a false online identity used for deceptive purposes: 

(Alguien que se hace una identidad falsa en Internet con propósito de ocultar la suya, para delinquir, o para crear corrientes de opinión insertándose en foros, todo muy manipulador o ilegal)

A sockpuppet is an online identity used for purposes of deception. The term, a reference to the manipulation of a simple hand puppet made from a sock, originally referred to a false identity assumed by a member of an internet community who spoke to, or about, himself while pretending to be another person. The term now includes other uses of misleading online identities, such as those created to praise, defend or support a third party or organization. A significant difference between the use of a pseudonym and the creation of a sockpuppet is that the sockpuppet poses as a independent third-party unaffiliated with the puppeteer.

The term "sockpuppet" was used as early as July 9, 1993 but did not become common in USENET groups until 1996. The first Oxford English Dictionary example of the term, defined as "a person whose actions are controlled by another; a minion," is taken from U.S. News and World Report, March 27, 2000.
