Please do not ask us to run checks without good reason; be aware of the following before requesting a check:

  1. Checkuser is a last resort for difficult cases; pursue other options first, such as posting on the administrator's noticeboard.
  2. Running a check will only be done to combat disruption on Commons, or as required to assist checkuser investigations on other Wikimedia wikis.
    • Valid reasons for running a check include, for example: vandalism where a block of the underlying IP or IP range is needed and suspected block evasion, vote-stacking, or other disruption where technical evidence would prevent or reduce further disruption.
  3. Evidence is required. When you request a check, you must include a rationale that demonstrates (e.g., by including diffs) what the disruption to the project is, and why you believe the accounts are related.
    • Requests to run a check without evidence or with ambiguous reasoning will result in delays or the request not being investigated.
  4. The privacy policy does not allow us to make a check that has the effect of revealing IP addresses.
  5. Requests to run a check on yourself will be declined.
Outcome

Responses will be brief in order to comply with Wikimedia privacy policy. Due to technical limitations, results are not always clear. Closed requests are archived after seven days.

Privacy concerns

If you feel that a checkuser request has led to a violation of the Wikimedia Foundation privacy policy regarding yourself, please refer the case to the Ombudsman commission.

If this page is displaying outdated contents even after you refresh the page in your browser, please purge this page's cache.

To request a check:

Cases are created on subpages of Commons:Requests for checkuser/Case.

Creating a request
  • 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 Commons: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.


Then transclude your subpage on the top of the list at Commons:Requests for checkuser and remove {{Checkuser requests to be listed}} from the top of the case subpage.

Rationale, discussion and resultsEdit

Reason: Same (copyvio) uploads concerning prefeitos and prefeitas from Category:São Paulo do Potengi, ClaudioMassena (talk · contribs) recategorizing two previous uploads from Eugênio Gouveia (talk · contribs) here and here. Patrick Rogel (talk) 00:02, 17 August 2019 (UTC)

HoriwikiEdit

Suspected related usersEdit

Rationale, discussion and resultsEdit

Reason: On 14 August 2019, Wikiokun uploaded File:三田杏華.png, which was eventually deleted as a copyright violation. On 15 August 2019, Horiwiki uploaded the similar image of the same person. The file, which is also likely a copyright violation, has the same title ("File:三田杏華.png") and description ("三田杏華着物姿"). Furthermore, ja:三田杏華 and ja:千広真弓 have been edited by both users. Horiwiki's first edit in eleven months in the Japanese Wikipedia is adding File:三田杏華.png again to ja:三田杏華 (see diff 1 and diff 2); the article was created just one day before. 153.174.6.103 03:56, 15 August 2019 (UTC)
