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.

Additional information needed Deferred to
 Doing… Pictogram voting info.svg Info
  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.


Gusstavo Rivas[edit]

Suspected related users[edit]

Rationale, discussion and results[edit]

Reason: All the accounts upload similar kind of inappropriate content (out of scope and with likely copyright issues). This is quite disturbing. Christian Ferrer (talk) 05:15, 19 June 2018 (UTC)

Pictogram voting info.svg Info I just came back from my job and found 4 or 5 other accounts, I decided to block all the accounts listed above. Christian Ferrer (talk) 11:10, 19 June 2018 (UTC)
Likely for Fredy saravia, Gianpierre.cahua, Gusstavo Rivas, Milena quina, Xarlyman. The rest is Symbol unsupport vote.svg Inconclusive. --Krd 11:15, 19 June 2018 (UTC)

Alastrina Leftwich[edit]

Suspected related users[edit]

Rationale, discussion and results[edit]

Single-purpose accounts related to "Lauwiner Empire" hoax.

Alastrina Leftwich (active 2016-05-03 to 2017-05-19) made several related uploads and ten edits on English Wikipedia. Most of them have been deleted, but based on available diffs, they were related to the hoax. (LE in "LE Enterprises & Co" standing for "Lauwiner Empire".) Although they have no edits there, the account was created through German Wikipedia, which makes sense as the user appears to be from Switzerland based on the involved IP addresses. I'm expecting this account to be stale, but including it for completeness and behavioral reference.

Andry Melnychuk (active 2017-06-03 to 2017-06-14) made a related upload. Apart from missing an attached account on, there are attached accounts on the same projects as for the suspected master. Like the suspected master, the user seems eager to sweep notices from their talk page under the rug. Expecting this one to be stale as well.

Michael Chabot (active 2017-06-14 to 2018-06-06) made several related uploads, attempted to sweep problems under the rug, commented on Commons:Deletion requests/Files uploaded by Michael Chabot after it was blanked out by, was blocked on Wikidata and requested unblocking (which was refused). (active 2018-06-04 to 2018-06-05) blanked out some instances of "fictional" from related media, created Category:Lauwiner Empire and linked it to Wikidata item Q54806194, which has since been deleted. (I can't see who created it, but I suspect it might have been "Michael Chabot".) Swiss IP address. (active 2018-06-04) made a single edit to Category:Lauwiner Empire. Swiss IP address. (active 2018-06-04 to 2018-06-06) edited Category:Lauwiner Empire and blanked out the contents of Commons:Deletion requests/Files uploaded by Michael Chabot.

Alfred.Delmore - Lauwiner Empire (active on English Wikipedia 2018-06-10 to 2018-06-11) made 64 edits to turn his user page into a fake article using files uploaded by "Alastrina Leftwich" and "Michael Chabot". Note the period in the username.

Edward Harrison 72 (active on Wikidata 2018-06-12 to 2018-06-13) created wikidata:Q54936010.

Steve.Hudgens (active 2018-06-13) made several related uploads, blanked out problem tags and instances of "fictional" from Category:Lauwiner Empire (and made an unblock request on meta despite not being blocked there). Note the period in the username.

Parzival.Knight (active 2018-06-16 to 2018-06-17) made a few token edits before jumping right into Commons:Categories for discussion/2018/06/Category:Lauwiner Empire to defend it, blanking out instances of "fictional" from the category, and adding related media to de:Gedenkmünze. Note the period in the username.

External links which may be relevant: and Looking at who reacted to the Facebook photos, Jonas Lauwiner seems to have connections to people in Switzerland and Ukraine, which matches with the IP addresses above, several of the token edits and the languages apparently spoken by the vandal.
