How Does a False Wikipedia Edit Reach Google?

What the edit histories show

Karmen Petrovic, the ring name of Monika Klisara, is a 30-year-old professional wrestler signed to WWE, where she works on the NXT and Evolve brands, and a member of Los Perros del Mal in Lucha Libre AAA. On 30 September 2026 wrestling sites and Yahoo Sports reported that she had briefly been listed as dead on Google and Wikipedia. She answered on social media, in a post Yahoo quotes as “the internet is a weird place.. sending everyone love & healing”. She is alive, and nothing in the record suggests otherwise.

Wikipedia keeps every version of every article, with a timestamp to the second and a note of what kind of account made each change, so the Wikipedia half of the story can be reconstructed exactly. We pulled the complete revision histories of her English and Portuguese articles through the public MediaWiki API on 1 October and compared each version with the one before it, word by word.

The first false edit was in Portuguese. At 22:43 UTC on 29 September a registered account added a date of death, “29 de setembro de 2026”, and a place of death, “Orlando, Florida”, to the article's infobox; three minutes later the same account changed the text to the past tense. Both rendered on the page. A different registered account removed them at 04:09 and 04:11 UTC on 30 September, 5 hours 26 minutes later.

English Wikipedia followed. At 00:30 UTC on 30 September a temporary account switched the opening of the article to the past tense (“was a Bosnian-Canadian professional wrestler”) with the edit summary “Made editing changes to a recently passed away individual”. It was reverted 54 minutes later. The same account came back four more times over the next 19 hours, at 04:36, 12:25, 17:38 and 19:42 UTC, each time adding a sentence saying she had died on 29 September in Orlando “surrounded by loved ones”, with no source. A sixth insertion, at 02:34 UTC, came from a different account, discussed below.

Each claim was removed, by a mixture of registered editors and other logged-out readers: of the ten edits that undid death claims that day, five came from temporary accounts, with summaries such as “There is no report of her death” and “Fixed the weird death hoax thing going on”. One registered editor used a counter-vandalism tool whose revert summary read “unsourced”. In all, 13 accounts made 19 edits to the English article on 30 September, on an article that had not been edited since 10 September.

Two other details matter for anyone thinking about their own pages. First, the clean-up was not always clean: one well-meant edit at 12:35 UTC removed the death sentence but also cut text from two sections, and it took an undo of 13 revisions at 14:43 to restore the article. Second, the loudest falsehood was not the most durable one.

At 02:51 UTC another temporary account replaced the name of the athlete the article gives as her partner with a different athlete's name, leaving the original citation in place. Nobody singled it out. It went only when the 14:43 undo swept away everything since midnight, almost 12 hours later. A death claim draws a crowd of correctors; a plausible-looking change to a detail does not.

Where Google comes in

Yahoo Sports reported that Petrovic “was reportedly shown on Google's Knowledge Panel as having died on September 29, 2026, in Orlando, Florida”, and that the false listings were “quickly removed”. We did not see the panel ourselves during the incident and cannot say when it changed, so that is reported secondhand. The date and place match the Wikipedia edits exactly.

The obvious assumption is that Google copied Wikipedia. Google's own documentation neither confirms nor rules that out. Its help page says knowledge panels are “automatically generated, and information that appears in a knowledge panel comes from various sources across the web”, sometimes combined with data from partners and from verified subjects, and that panels are “updated automatically as information changes on the web”. It does not name Wikipedia, Wikidata or any other source, a point examined in how an entity gets into the Knowledge Graph.

The edit histories add one awkward fact. At 02:34 UTC a temporary account that had not otherwise touched the article added the same date and place of death to the English infobox with the edit summary “death date from google”. At that moment the English article had no date of death in it; the earlier past-tense edit had been reverted an hour before. The Portuguese article did carry the date. We cannot tell what that editor saw, or where Google had found it, but taken at face value the summary describes a false fact travelling from Google into English Wikipedia. A loop like that is how a false fact can look corroborated: each copy appears to confirm the other.

What the false fact did not reach is also measurable. Wikidata, the structured sister database that holds facts such as dates of birth and death in machine-readable form, and whose entry for Petrovic carries a Google Knowledge Graph identifier, recorded no edit at all. Its last change before the incident was on 17 July 2026, and it has never held a date-of-death statement for her. Whatever route the false date took to Google, it was not through Wikidata. Why Wikidata is a separate and differently policed layer is covered in is Wikidata easier to get into than Wikipedia.

Why the claim kept coming back

Wikipedia's policy on biographies of living persons is unambiguous about this kind of material. Contentious material about living people that is “unsourced or poorly sourced” must be “removed immediately and without waiting for discussion”, whether it is negative, positive, neutral or “just questionable”. That is what happened, six times. The policy governs removal; it does not stop the next insertion.

The tools that do stop it are protection levels, applied by administrators on request. Semi-protection blocks edits from logged-out users and from accounts less than four days old or with fewer than ten edits. Pending changes protection lets such users edit but holds their changes until a reviewer accepts them, so that, in the policy's words, they are not visible “to most readers” in the meantime. According to the article's logs, neither was applied at any point on 29 or 30 September; the only entries are from its creation in 2023.

The repeat editor was a temporary account, the kind Wikipedia now assigns to logged-out editors in place of showing their IP address. Wikipedia's own description is that a temporary account lives in a browser cookie and cannot be used from another browser or device, which suggests the same browser came back for 19 hours. A registered editor posted on the account's talk page at 13:16 UTC asking it to stop. Two more insertions followed. An administrator blocked it indefinitely as a “vandalism-only account” at 20:25 UTC, 16 minutes after the last revert and nearly 20 hours after its first edit.

What this means for an executive or a company

Nothing about this mechanism is specific to wrestlers, or to deaths. A founder's biography or a company article can be edited to say the founder has resigned, the company has been acquired or a product recalled, and the same three things are true: the edit is live the moment it is saved, readers and search features can pick it up before anyone notices, and a quiet, plausible falsehood is likely to last longer than a dramatic one. Four practical points follow from the records.

Watch the page, not just the search result. Wikipedia lets anyone with an account add a page to a watchlist and see every change made to it. The English death claims lasted minutes because thousands of readers were looking; a company article with a dozen daily readers may have no one looking at all. Monitoring of this kind is covered in ongoing monitoring.

Know what you are allowed to fix yourself. Wikipedia's conflict-of-interest guideline lets connected editors make “unambiguously uncontroversial edits”, including removing “unambiguous vandalism” and “unambiguous violations” of the living-persons policy, while pointing paid editors to a stricter rule. A false death is unambiguous. A disputed figure is not, and belongs on the article's talk page with an {{Edit COI}} request, or at the biographies of living persons noticeboard, which is where Wikipedia's own page for article subjects sends people. The rules on paid help are in can you pay someone to edit your Wikipedia article.

Ask for protection when it repeats. Any user can request page protection. Here the same account made five insertions over 19 hours; by the second or third return the page arguably fitted the policy's description of “heavy and persistent vandalism”, but no one asked. Protection is temporary and can be set to expire.

Fix Google separately. Correcting Wikipedia does not instantly correct Google, and Google does not promise that it will. Anyone can flag a panel fact through the Feedback link; a subject who has claimed and verified the panel can use Suggest edits, describe “What's wrong with the existing information” and give “publicly accessible URLs that support your suggestion”. Google says it reviews verified feedback “within a few days” and that it “can sometimes take more time”. Claiming is only possible where Google offers it (“Not all knowledge panels are claimable as of now”), which is a reason to claim a panel before you need to. The process is described in the Google knowledge panel, and why AI assistants offer nothing comparable in can a company correct what an AI says about it.

Petrovic's own response, a single good-humoured post, is also worth noting as crisis communication: the false claim was about her, simple to refute, and she refuted it in public within hours. A company facing a false claim of similar simplicity has the same option, and it creates the “publicly accessible URL” that Google's correction process asks for.

Methodology and limitations

On 1 October 2026 we retrieved, through the public MediaWiki API with a descriptive user agent, the revision history of the English Wikipedia article “Karmen Petrovic” (page 75630125) back to June 2026, the full text of every revision from 10 September (1374144653) to 30 September (1377723170), the article's log entries and protection status, and the block log of the account that made five of the insertions. We did the same for the Portuguese article (revisions 73086941 to 73089177) and checked the Spanish, Arabic and Hebrew articles, none of which carried a death claim; the Spanish one received an unrelated nonsense insertion on 30 September. We read the Wikidata item Q123985867 and its revision history. We compared consecutive revisions word by word and rendered the key revisions through the API to confirm which false fields were visible to readers. Durations run from the timestamp of the false edit to that of the edit that removed it, in UTC; where removal was partial we say so. We classified accounts only as registered or temporary, as the API reports them, and do not name editors. Page views are from the Wikimedia pageviews API for the “user” agent type; figures for 1 October were not yet available. Five limitations apply. We could not observe Google's knowledge panel during the incident, and what it showed is taken from Yahoo Sports. We cannot establish the source Google used, or what the editor who cited Google saw. Slam Wrestling was read in part; webisjericho.com and itrwrestling.com refused our requests, so the wrestling press was read secondhand through Yahoo Sports and Brave search summaries. We did not contact Petrovic, WWE, Google or any editor. And one incident on one biography is a case study, not a measurement of how often false facts reach Google.

Conclusion

The Wikipedia record of Karmen Petrovic's false death is precise in a way such stories rarely are. Seven insertions across two languages over 21 hours; English claims removed in between under five and 54 minutes each, two hours 18 minutes in all; a Portuguese claim that lasted five and a half hours; one persistent logged-out account, blocked only after its fifth attempt; no page protection; and no change at all to Wikidata. What it cannot show is how the false date reached Google, and the one clue in the record, an edit justified as “death date from google”, points the other way from the usual assumption. For a company or an executive the useful lessons are practical rather than technical: watch the pages that describe you, know which edits you may make yourself, ask for protection when vandalism repeats, claim your knowledge panel before you need it, and expect a quiet false detail to outlive a loud one.
