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.

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 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.

Rationale, discussion and results

    One of the latest crosswiki socks is Lexuel, meanwhile they've likely created Dliurp to remove the no permission template from the file. Titore (talk) 06:15, 30 July 2026 (UTC)
    They keep creating new accounts to upload pictures of Angie, I just added Rerelo. --Titore (talk) 05:45, 31 July 2026 (UTC)

Reason: A user uploading images with various Zatony accounts. There may well be more around, but I was only able to find these two at the moment. זיו「Ziv」 • For love letters and other notes 19:27, 27 July 2026 (UTC)

SamsungBerdaiOthmane

Status: open • view • edit • history • watch
Filed: 15:00, 26 July 2026 (UTC)

Rationale, discussion and results

Reason: We have a large group of socks. This user creates a new account each time and uploads only a few files. These are usually downgraded versions of existing files. The new file names and / or Username often contain variations of the spammer's name, "Berdai Othmane", "BerdaiOthmane", "Berdai-Othmane" etc. Besides self-promotion, there are also ads for online marketplaces and microfinance organizations. I don't know which account is the primary one. I've only listed a partial list of accounts. There are most likely many more. IP address blocking is necessary if confirmed. Self-portrait of this spammer
George Chernilevsky talk 15:00, 26 July 2026 (UTC)

 Comment He also uploaded images from the Internet (see here or here). These are mostly logos and/or graphics associated with specific companies. I believe blocking the IP address is a very sensible measure to prevent unnecessary “out-of-scope” material in the future. DimiDimi (talk) 18:37, 26 July 2026 (UTC)
Already on behaviour this is clearly a sock farm of burner accounts, many of them Stale, Udona.ma does not exist. I will block and tag the lot on behavior. There is no reasonable IP or IP range to be blocked. I identified two sleeper accounts, Tmobilemosqueezoubir1 and PorscheBlue that will be blocked as well. --Lymantria (talk) 07:54, 27 July 2026 (UTC)
 Info I meant Uduno.ma (talk • contribs • Luxo • SUL • deleted contribs • logs • block user • block log). And actually there are more accounts. DimiDimi (talk) 15:53, 27 July 2026 (UTC)
