This page is for requesting that we investigate whether two or more Wikipedia accounts are being abusively operated by the same person.
Before opening an investigation, you need good reason to suspect sockpuppetry.
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, checkusers will not publicly connect an account with an IP address per the privacy policy except in extremely rare circumstances.
Use this section to request checkuser information relating to a situation that does not involve sock puppetry. You could use this section to request, for example:
For threats of harm (to self or others) you must email emergencywikimedia.org (see the threats of harm page) and not use this page. Requests to investigate and confirm sockpuppetry should be listed in the sockpuppet section above, and not here (such requests will be summarily removed).
To make a request here, copy the following template and paste it to the end of this section (quick link to edit) – replacing "header" with an informative title, and adding underneath the template any relevant information – then sign using "~~~~", preview, and click "save".
