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.
