Commons:Requests for checkuser


Does your request belong here?
This is the place to request sockpuppet checks or other investigations requiring CheckUser privileges. Checkuser is a last resort for difficult cases. Use other methods first. You can try posting on the administrator's noticeboard for example.
Please do not ask us to run checks without good reason:
These indicators are used by CheckUsers to allow easier at-a-glance reading of their notes, actions and comments.

  1. 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 vandalism where a block of the underlying IP or IP range is needed, disruptive sockpuppetry, vote-stacking, and similar disruption where the technical evidence from running a check would prevent or reduce further disruption to Wikimedia projects.
  2. Requests to run a check with ambiguous reasoning will result in delays - please provide a rationale at the time you make the request
    • Show what the disruption to the project is, and why you believe the accounts are related.
  3. Requests to run a check on yourself will be declined
  4. The privacy policy does not allow us to make a check that has the effect of revealing IP addresses.
Responses will be brief in order to comply with Wikimedia privacy policy. Due to technical limitations, results are not always clear. Check back regularly to see the outcome of your request. Closed requests are archived after seven days.
Privacy violation?
If you feel that a checkuser has led to a violation of the Wikimedia Foundation privacy policy regarding yourself, please refer the case to the Ombudsman 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 (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.

Suspected related usersEdit

Rationale, discussion and resultsEdit

Reason: Block evasion, 3rd CU request regarding Blackwhiteupl who in the meantime was found to be identical to Kay Körner. --Achim (talk) 17:29, 22 August 2016 (UTC)

  • Confirmed - no sleepers. Эlcobbola talk 17:38, 22 August 2016 (UTC)

Blossom goodEdit

Suspected related usersEdit

Rationale, discussion and resultsEdit

Reason: Both thee users has uploaded non-free images of Erin Sanders from the same website ( and tagged the author as {{unknown|author}}. Josve05a (talk) 02:57, 22 August 2016 (UTC)

  • Declined - The images are different, have different file names, and have different technical characteristics (e.g., Blossom good is contributing through Wikipedia Zero, MattSalzani is not). Looking at other possible evidence, Blossom good was blocked 22. August, but MattSalzani was created 4. August, so timing does not suggest circumvention. Blossom good's edits are related to pop culture/actors, whereas MattSalzani's edits are related to hockey. An image of Erin Sanders is the only overlap. At this point, there is simply not enough evidence. If further evidence arises, please feel free to update the request. Эlcobbola talk 03:53, 22 August 2016 (UTC)
    •  Comment The block on August 22 was performed by me minutes before this "request". But I understand that there might not be reson enough for a CU, but I though should report/request it anyways, just in case. Josve05a (talk) 03:58, 22 August 2016 (UTC)
      • Yes, I'm aware. And that's the point: MattSalzani arose independent of any block or sanction, which is not what one would expect if it were a sock. Эlcobbola talk 04:41, 22 August 2016 (UTC)

Rationale, discussion and resultsEdit

Reason: Comes back all the time with new accounts to upload fake flags. See Category:Sockpuppets of Szm020730. Could you check if this guy can be kicked off the Wiki with some rangeblock without causing trouble to other users? Jcb (talk) 17:01, 20 August 2016 (UTC)

The user is indeed on a lot of ranges, some of which have been blocked. Please report future occurrences. (I'm watching the category now, too.) --Krd 06:48, 22 August 2016 (UTC)


Suspected related usersEdit

Rationale, discussion and resultsEdit

Reason: These few users have reuploaded the same files over and over again. Some of them were blocked by -revi for abusing multiple accounts on kowiki and Commons. I suspect there might be more socks and sleeper accounts. Jianhui67 talkcontribs 11:11, 24 August 2016 (UTC)

@-revi: Please comment. Thanks. Jianhui67 talkcontribs 11:11, 24 August 2016 (UTC)

I added few more accounts I've blocked. I'll add some more as I find them. — regards, Revi 11:32, 24 August 2016 (UTC)

User is a known LTA on kowiki of real sockmaster being "정현규". He's evading blocks with 50+ socks, which is a good reason to believe there are more socks. (kowiki has strict rules on CU so I don't try to ask CU there.) Details for deleting files on Commons is on COM:Deletion requests/Files uploaded by 옆쪽무쪽.— regards, Revi 11:45, 24 August 2016 (UTC)
No socks found. (Some of the listed accounts are stale.) --Krd 12:53, 24 August 2016 (UTC)
