Sock puppetry can take on several different forms:

The misuse of multiple accounts is considered a serious breach of community trust. It may lead to:

Editors must not use alternative accounts to mislead, deceive, disrupt, or undermine consensus. This includes, but is not limited to:

Alternative accounts have legitimate uses. For example, editors who contribute using their real name may wish to use a pseudonym for contributions with which they do not want their real name to be associated, or long-term users might create a new account to better understand the editing experience from a new user's perspective. These accounts are not considered sockpuppets. If you use a legitimate alternative account, it is your responsibility to ensure that you do not use it in an illegitimate manner according to this policy.

Valid reasons for an alternative account include:

Alternative accounts should always be identified as such on their user pages, except where doing so would defeat the point of the account. Templates such as {{}} or one of a selection of user boxes may be used for this purpose.

If you have concerns that an IP editor is actually a user with an account who is editing while logged out in a way that is inappropriate, you can give the IP editor notice of this policy (), and if the behavior continues, you should contact a CheckUser privately and present the evidence to them.

Except when doing so would defeat the purpose of having a legitimate alternative account, editors using alternative accounts should provide links between the accounts. Links should ideally take the form of all three of the following:

Editors who have multiple accounts for privacy reasons should consider a checkuser or members of the arbitration committee if they believe editing will attract scrutiny. Editors who heavily edit controversial material, those who maintain single purpose accounts, as well as editors considering becoming an administrator are among the groups of editors who attract scrutiny even if their editing behavior itself is not problematic or only marginally so. Concerned editors may wish to or any individual with checkuser rights. Editors who have abandoned an account and are editing under a new identity are required to comply with the clean start policy.
