"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 an independent third-party
unaffiliated with the puppeteer."
