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.

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.
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.

Reason: All of them uploaded photos of non-notable you-tuber BrazyXay. They all are trying to promote the same by creating wikidata item and enwiki draft for the same. QueerEcofeminist "cite! even if you fight"!!! [they/them/their] 05:51, 6 August 2020 (UTC)

Reason: LTA case; there's been a spate of recent accounts so seeing if a rangeblock might be possible. @Bsadowski1, Stryn, Martin Urbanec, Schniggendiller: courtesy ping since you've all been involved with their crosswiki abuse. Pi.1415926535 (talk) 01:41, 4 August 2020 (UTC)

  • I'm inclined to decline--not for any pejorative reason, but because 1) this is a well-known LTA who uses disposable IPs (i.e., range blocks not expected to be useful) and, conversely, for whom any potentially effectual range blocks have already been made and 2) the x-wiki nature of this LTA means handling/range blocks/etc. would be better made at the Meta level, not at the Commons. I'll leave this for other CUs to opine. Эlcobbola talk 15:08, 6 August 2020 (UTC)
    • Thanks for the detailed explanation - I appreciate your experience and wisdom here. Pi.1415926535 (talk) 20:03, 6 August 2020 (UTC)

Reason: The accounts upload similar files. All of them are images of Japanese businesspeople, celebrities, racecars, aircrafts, and/or company logos. All accounts indiscriminately license their images under CC-BY-SA as their own work. Many of these images have been proven to be not their own works and were found elsewhere on the Internet.

Masahiro007 and Ka04iso10 both have worked on drafts for the English Wikipedia article on Swift-Xi. See [1] and [2].

Masahiro007 and ShyujiTanaka both have uploaded an image named "Hiroyuki Matsushita.jpg". Masahiro007 uploaded first, which got deleted, and was then uploaded again by ShyujiTanaka. See [3] and File:Hiroyuki Matsushita.jpg. FunnyMath (talk) 16:52, 25 July 2020 (UTC)

Masahiro007 and ShyujiTanaka both uploaded photos which were then used in the Hiro Matsushita English Wikipedia article.

Masahiro007, Swift Enginnering and Carnumber21 both uploaded photos which were then used in the Swift Xi English Wikipedia article. FunnyMath (talk) 17:01, 25 July 2020 (UTC)

Masahiro007 and Yuji Yoshida both uploaded photos which were then used in the Swift Engineering English Wikipedia article. FunnyMath (talk) 17:29, 25 July 2020 (UTC)

An administrator suspected that Hyogo Press may be a sockpuppet of Masahiro007 due to similar uploading behaviours. See [4]. In one example, Hyogo Press uploaded File:Konosuke Matsushita founder of Panasonic.jpg around the same time as Masahiro007 uploaded File:Masaharu Matsushita.jpg. Both files were images of Panasonic presidents. FunnyMath (talk) 22:00, 25 July 2020 (UTC)
