Sockpuppet investigations is for requesting an investigation of whether two or more Wikipedia accounts are being abusively operated by the same person. This process is described in some length at the guide.

Before opening an investigation, you need good reason to suspect sockpuppetry.

1. Evidence is required. When you open the investigation, you must immediately provide evidence that the suspected sock puppets are connected. The evidence will need to include diffs of edits that suggest the accounts are connected. (This requirement is waived if the edits in question are deleted; in this case just provide the names of the pages that the accounts have been editing.)
2. You must provide this evidence in a clear way. Vaguely worded submissions will not be investigated. You need to actually show why your suspicion that the accounts are connected is reasonable.
3. Concision is key. Evidence should be presented in a concise format. Because of the length of the backlog, cases with clear and concise explanations and evidence are handled the most quickly.

Investigations are conducted by a clerk or an administrator, who will compare the accounts' behaviour and determine whether they are probably connected. Upon request, investigations can also be conducted by a checkuser, who can look at technical data behind the accounts in order to determine how likely it is they are connected. CheckUser results are often called technical evidence, in contrast to publicly available behavioural evidence.

Due to Wikipedia's CheckUser policy, checkusers will conduct a technical investigation only if clear, behavioural evidence of sockpuppetry is also submitted; if you ask for technical evidence to be looked at but do not provide behavioural evidence, the investigation may not be allowed to proceed. Additionally, per the privacy policy, checkusers will not publicly connect a named account with an IP address or temporary account, except in extremely rare circumstances.

How to open an investigation

To add to an existing investigation (or case), enter the case name in the box below. To create a new investigation, enter the username of the oldest-created registered account (the "sockmaster")—or, if only IP addresses are involved, the IP that made the first relevant edit. Then click "Submit". Note: Do not include "User:" or any other commentary.

For example, if a prior filing was at Wikipedia:Sockpuppet investigations/John Doe, or this is a first filing and the oldest registered account is User:John Doe, you should enter John Doe in the box below.

You will then be taken to another page containing a form you must complete to open the investigation. The process for opening a subsequent investigation on the same user is the same as for creating a new case. Again, do not include "User:" in any of the numbered fields.

You do not need to notify the accused editors that you have opened an investigation on them, and in most cases should not. An administrator or clerk can handle this if necessary.
