"This policy in a nutshell:
Do not use multiple accounts to create the illusion of greater support for an issue, to mislead others, or to circumvent a block. Do not ask your friends to create accounts to support you or anyone else.

A sock puppet is an additional username used by a Wikipedian who edits under more than one name. The Wikipedian who uses a sock puppet may be called a sock puppeteer. Use of sock puppets is discouraged in most cases. Jimbo Wales has said: "There's no specific policy against it, but it's generally considered uncool unless you have a good reason," and " ... multiple usernames are really only a problem if they are used as a method of troublemaking of some sort. For example, to generate an appearance of consensus, or to vote more than once, or to hide from public scrutiny." [1]
