Information
Additional information needed Deferred to
 Doing… Info

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. (This is not a venue for requesting administrative action such as blocks or file clean-up.)
  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.
    • Requests to check accounts already confirmed on other projects may be declined as redundant.
    • Requests to run a check on yourself will be declined.
  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.

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 Ombuds commission.

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 using {{subst:Commons:Requests for checkuser/Inputbox/Sample}} (if the case has been archived). When editing an existing case, be sure to list/transclude the subpage here.
Transcluding the request
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.

Aokoroko

Status: resolved • view • edit • history • watch
Filed: 12:36, 7 July 2026 (UTC)

Rationale, discussion and results

Reason: both accounts are used in similar and very specifical threads - Mandelbrot set. The user page Majow was created by user Aokoroko. The user Majow has voted only twice on the FPC, and both times for nominations by user Aokoroko. It very much like a sock behavior. I would like to be wrong because i like images by Aokoroko. George Chernilevsky talk 12:36, 7 July 2026 (UTC)

I only became acquainted with Aokoroko through his activity on the German Wikipedia article about the Mandelbrot set. It is not entirely clear to me why he edited my user page. I consider this behavior intrusive, though perhaps he wanted to obscure the fact that I might not actually be eligible to vote. I have made very few contributions on Wikimedia.org, and most of them relate solely to the Mandelbrot set. I taught Aokoroko the new methods required for creating deep-zoom images of the Mandelbrot set. Earlier today, I rejected another change he made to the Wikipedia article, so I thought I could at least support his image. Naturally, if I turn out not to be eligible to vote, I will withdraw my support. Majow (talk) 13:01, 7 July 2026 (UTC)

Sorry! I thought I... Aokoroko (talk) 13:20, 7 July 2026 (UTC)
Sorry! Excuse me! Aokoroko (talk) 13:23, 7 July 2026 (UTC)
I absolutely welcome the CheckUser investigation because I have zero technical or personal connection to user Majow.
In fact, the accusation of us being the same person or colluding is completely refuted by our recent editing history on the German Wikipedia article de:Mandelbrot-Menge. Just yesterday (July 6, 2026), we had an edit war where Majow reverted my contribution and strictly rejected the addition of my extreme-zoom fractal images to the article, stating they were "not necessary".
Majow is an active, long-term main contributor to that mathematical article. It is only natural that they monitor Mandelbrot-related threads on Commons. While they might have appreciated some of my imagery in FPC votes, our content-driven disagreements on dewiki prove that we are entirely separate individuals with different viewpoints. Please run the technical check to clear my name. -- Aokoroko (talk) 13:03, 7 July 2026 (UTC)

Rationale, discussion and results

Reason: They both uploaded the same file:King Lil G.jpg. Now Westcoastfan is only warned, but if they are related, then he must be indefinitely blocked. Taivo (talk) 09:29, 7 July 2026 (UTC)

Same file name but different image. Westcoastfan has only one deleted upload. I think this should be declined. Krd 13:40, 7 July 2026 (UTC)

Rationale, discussion and results

Reason: Spammer using exactly the same pattern: Creating a userpage of a few lines containing a weblink and uploading a logo. All edits within about an hour. Please check for others I don't see. --Achim55 (talk) 16:01, 25 June 2026 (UTC)
