Requests for checkuser

This is the place to request investigations of abuse of multiple accounts or of other circumstances that require use of checkuser privileges.

Requesting a checkuser

---

Please don't ask us to run checks without good reason; be aware of the following before requesting:

1. Checkuser is a means to choose for difficult cases. If multiple accounts show clear behavior patterns or editing type, please post on the administrator's noticeboard.
2. Running a check will only be done to combat disruption on Wikidata, or as required to assist checkuser investigations on other Wikimedia wikis.
   • Valid reasons for running a check include, for example: 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. Do not post requests for fishing without any grounds.
4. The privacy policy does not allow us to make a check that has the effect of revealing IP addresses. Do not post requests to compare IPs to accounts or IPs to IPs comparisons.
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.

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 checkuser

---

Cases are created on subpages of Wikidata: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 at the bottom.

Example

If you want to request a checkuser on User:John Doe, enter the text Wikidata:Requests for checkuser/Case/John Doe then click "Make a checkuser request". You will be taken to a page where you can fill out the request. Please make your request there brief and concise.

Translate this header box!

Rationale, discussion and results

Reason: The data maybe will be probably stale, but I'll try: today I noticed a situation on the Spanish Wikipedia involving the item Q124608071, and upon closer examination of the item's history on Wikidata, it shows constant deletions and additions by interwikis, and further back, there are accounts globally blocked as sockpuppets of BilouB.

I don't know if this LTA has intervened in other articles on other projects, but I suspect that at least the first account on the list is collaborating very closely with the person represented in the item, almost in the same way as the master. Taichi (talk) 19:18, 21 December 2025 (UTC)

Results: Unfortunately, all but one account is Stale. The evidence you presented against AngelaMx (the only non-stale account) is not enough to justify a check; you will need to be more specific, and that assumes there is archived data for the master. Declined for now.--Jasper Deng (talk) 11:34, 22 December 2025 (UTC)
