This is the place to request sockpuppet checks or other investigations requiring CheckUser privileges. Checkuser is a last resort for difficult cases. Use other methods first: for example you can try posting on the administrator's noticeboard.
Please do not ask us to run checks without good reason:
These indicators are used by CheckUsers to allow easier at-a-glance reading of their notes, actions and comments.
Running a check will only be done to combat disruption on Wikispecies, or as required to assist CheckUser investigations on other Wikimedia wikis.
Valid reasons for running a check include vandalism where a block of the underlying IP or IP range is needed, disruptive sockpuppetry, vote-stacking, and similar disruption where the technical evidence from running a check would prevent or reduce further disruption to Wikimedia projects.
Requests to run a check with ambiguous reasoning will result in delays – please provide a rationale at the time you make the request.
Show what the disruption to the project is, and why you believe the accounts are related.
Requests to run a check on yourself will be declined
The privacy policy does not allow us to make a check that has the effect of revealing IP addresses.
Outcome
Responses will be brief in order to comply with Wikimedia privacy policy. Due to technical limitations, results are not always clear. Check back regularly to see the outcome of your request. Closed requests are archived after seven days.
Privacy violation?
If you feel that a checkuser has led to a violation of the Wikimedia Foundation privacy policy regarding yourself, please refer the case to the Ombudsman commission.

Insert the name of the suspected sockpuppeteer (the main account or puppetmaster, not the sockpuppet!) in the box below, leaving out the "User:" prefix. Do not remove the text in the box, add to the end only.
Please explain/justify the request by saying what it is you suspect and why it is important that the check be carried out. Indicate the usernames you suspect, using {{checkuser}}. Please do not use this template in the section header, as that makes it difficult to read the account names. Include the diffs or links required to support the request and reason for it.
There are people to assist you and help with maintenance of the page. Just ask for help on the admin noticeboard if you really are stuck, or take your best shot and note that you weren't completely sure of what to say.
If a case subpage already exists, edit the existing page instead, either adding to the currently open section (if the case is not yet archived) or adding a new section to the top (if the case has been archived). When editing an existing case, be sure to list/transclude the subpage here.
Example
If you want to request a checkuser on User:John Doe, enter the text Wikispecies:Requests for checkuser/Case/John Doe then click "Request a checkuser." You will be taken to a page where you can fill out the request. Please make your request there brief and concise.
