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.
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 results

Reason: same pattern (re-creating the category and uploading a file), might be other accounts as well. Bencemac (talk) 19:36, 2 April 2026 (UTC)

 It looks like a duck to me, IAmJollie tagged, was already locked. --Lymantria (talk) 06:07, 3 April 2026 (UTC)

Rationale, discussion and results

Reason: vandal/nastiness accounts with same modus operandi: including that both vandalized File:January 2025 Official Vice Presidential Portrait of JD Vance.jpg , then vandalized Commons:Administrators' noticeboard/Vandalism identically once reported.

What I'd like to do here is form the basis for an IP range block, if possible; I don't know under current rules if CU will be any use, because I gather that we no longer can discuss the particular IPs associated with particular accounts. If there is no imaginable way to get from conclusions drawn here to an IP range block, then don't even bother. Jmabel ! talk 04:21, 25 March 2026 (UTC)

I found Confirmed:
and very Likely to these
All these accounts are already blocked and/or globally locked. They use different IPs in several ranges and those are taken care of (often by the stewards). I'll move the case to Jamesond88 and tag accordingly. --Lymantria (talk) 07:50, 25 March 2026 (UTC)
P.S. @Jmabel Checkusers cannot discuss IPs, IP ranges or temporary accounts in public. That does not mean they don't take measures like (requesting global) range blocks. --Lymantria (talk) 14:29, 25 March 2026 (UTC)
@Lymantria: Thanks, but I'd like to add Imu Nerona (talk • contribs • Luxo • SUL • deleted contribs • logs • block user • block log), who just vandalized this page.   — 🇺🇦Jeff G. ツ please ping or talk to me🇺🇦 17:06, 28 March 2026 (UTC)
Just so you know, the accounts are actually made by Zjholder, who is an LTA (long-term abuser) and does CWA (cross-wiki abuse) with his disruptive edits. NX3710 (talk) 00:48, 29 March 2026 (UTC)
Imu Nerona is Confirmed to these accounts. Thank you, NX3710, for pointing to Zjholder. From data I have seen, I can confirm this case to Zjholder. Will move this case and retag socks. --Lymantria (talk) 07:23, 29 March 2026 (UTC)
