|Someone is wrong on|
Originally used as a term to describe second identities, it is now used for any account created exclusively to cause mischief or mayhem at a site without the original user being identified (IP recognition and blocking notwithstanding).
The name has also led to sites that generate such users being referred to as a "sock drawer". Clever, that.
The reasons for sock puppetry can include:
- Rigging voting results
- Rigging discussions (creating a sockpuppet who "agrees" with your argument)
- Maintaining a separate identity for privacy reasons
- LANCB - but returning under an assumed sock
