Between 2009 and 2015, wrote eight articles about minor developer Ian Bogost, namedropping him at least nine more times, without disclosing their work together at Gamasutra.

Positive coverage of Zoe Quinn in three articles, without disclosing their friendship and eventual affair. Later covered Quinn again, disclosing they "dated briefly", but not that he had previously financially supported her.

Agenda driven non-interview of Ubisoft’s Mark Thompson, titled “Ubisoft refused to talk to me about women”, spent entirely offering his proofless, subjective prospective on things his subject allegedly didn't say. This piece followed another controversy-chasing article—over a nonissue—by Grayson, who had also previously engaged in a discussed, interrupted interview with Blizzard. By its timing, the Ubisoft interview may have been the cause of Kotaku’s claimed blacklisting.

Often accused of plagiarism because one article of his directly copies text from a French one. However, the original plagiarism was by the author of the Imgur post that Grayson quoted as source.

Wrote two times about Sunset, without disclosing her friendship with fellow journalist and occasional Kotaku contributor Leigh Alexander, who was involved in the game through her consulting company Agency for Games.

Wrote two articles about games by the controversial Mattie Brice, initially disclosing their friendship only in the first one — which is liked in the second. Article was updated with disclosure as well in 2015.

An article under the byline “Kotaku Staff”, written on February 2014—after Hernandez joined Kotaku—promoted Kopas again without disclosure. Hernandez covered Kopas again on April 2016, but in this time she disclosed that she and Kopas worked together on a book.

Wrote the perhaps most famous article on the Max Temkin accusations, where she claimed Temkin ”spent too much time defending himself, and not enough time contemplating the idea that he might‘ve messed up“. Article was later amended, and Kotaku admitted it was a misfire.

Sensationalist article criticizing of the use of the word "rape" as an euphemism for "one-sided victory" in online gaming.

His followup article after the end of the trial for the false Brad Wardell accusations echoes the false narrative of Kotaku's original piece by Kate Cox and completely inverts the real timing of the lawsuits.

Following allegations of cronyism between Brandon Boyer and Stephen Thirion, he wrote an article minimizing the issues, calling them "misguided at best" and comparing them to a conspiracy theory, since the person used as a source to confirm these ties denied having discussed them when he asked. Hasn't updated the article or returned on the subject when more proof of Thirion and Boyer's relationship surfaced — not only confirming this relationship existed and showing that Thirion had received coverage from Boyer multiple times, but that Boyer was involved in at least five other conflicts of interest of comparable magnitude.

Initiated a moral panic surrounding the game Dragon’s Crown—first, on Kotaku, by comparing the art direction of the game’s artist and Vanillaware president George Kamitani to the work of a “14-year-old-boy”. After a response from Kamitani and some backlash, Schreier doubled down with a longer article—which included an apology for his tone—and, especially, with some infamous forum posts where he accused the game’s large-chested sorceress character of inciting pedophilia. His criticism generated much backlash, with his Editor-in-Chief eventually addressing it, stating Schreier had been misunderstood.

Wrote two articles about a specific scene in the 2013 Tomb Raider prequel, eventually taking his reporting into scandalmongering territory.

Wrote a heavily circulated article about Trendy Entertainment, and a couple of follow-ups. In these articles,his anonymous sources described lots of issues at the “Video game studio from hell”, laying all the blame on then-president Jeremy Stieglitz. Issues included unfair crunch hours, bad management decisions, and, worst of all, offering lower wages to women candidates for the same positions. In 2016, a throughly researched article showed most of Schreier’s claims were heavily questionable: several of his sources were working at a competitor of Trendy, the woman offered a lower wage was significantly less qualified, and Trendy’s mismanagement seemed to come from individuals other than Stieglitz. Stieglitz lost his position immediately after the article, while actually still working for Trendy and being forced to co-operate with the people who had defamed him. The article was also eventually brought as evidence when Insight (Trendy’s owner) sued Stieglitz and the more-successful company he had founded, forcing him to settle for 40 million dollars.

Handwaved the Grayson sex scandal, claiming it wasn't an ethical issue because Grayson's article about Quinn was not a review and it was written on March 31, when they were just professional acquaintances.

Claimed that harassment caused Brianna Wu to leave her home, despite her history of farfetched claims and the ambiguous circumstances of the doxing, and never updated the article despite the the very strong evidence that, apart from an already planned weekend at Comicon, she had never actually left her home, aside from the numerous outrageous claims and apparent false flags that mined Wu’s credibility afterwards.

His comments on the response to Kotaku's article on Denis Dyack that he edited claimed that the article didn't accuse Dyack of embezzling money from publishers.

Baited into an article with a joke press release. Has promptly admitted the mistake and updated the article.

Initially handwaved the Doritosgate scandal as "not important" and "tired nonsense" — later retracting the statement after significant backlash, and producing perhaps the most exhaustive article on the subject, used as a source on DeepFreeze's own article as well.

Provided Kotaku's entry in the Gamers are dead media blitz, a brief article mostly quoting Leigh Alexander's.

Criticized detractors of the Call of Duty series — calling them "stupid", "idiots", "obnoxious elitist[s]" and even "asshole[s]" while his site was running an extensive Call of Duty ad campaign.

Advocated for the censorship of the Tentacle Bento card game, arguably contributing to its Kickstarter's cancellation.

Rewrote basically the same article on "Project Cars" over six times.

Covered the videogame Volume, which was a customer of Agency for Games—a company owned and founded by fellow journalist Leigh Alexander. Agency’s involvement in the Volume’s design has been confirmed by Bithell to have started prior to when Hamilton covered the game. Alexander and Hamilton have a very friendly relationship—exchanging tweets since 2009, meeting extremely frequently, working together. Hamilton’s article on Volume contains no disclosure of this relationship. Hamilton also covered Alexander directly several times—articles about Alexander contain very partial disclosures, while namedrops don’t disclose anything.

Wrote an article promoting a visual novel by Christine Love, without disclosing an apparently fairly developed friendly relationship—including frequent social media interactions, at least a meetup, and possibly more soon after the article.

Wrote about the doxing of actress Felicia Day following her blog post criticizing GamerGate. Took GamerGate's guilt as granted, despite it being impossible to prove and GamerGate hubs having mild reactions to Day's blog, universally condemning people calling for a reaction to it as shills and immediately condemning the dox. Hamilton also claimed the lack of harassment towards certain GamerGate critics as a point against the consumer revolt, and that the harassment targeting GamerGate activists was irrelevant in comparison. While the claim that Day was not actually doxed, with the leak containing data referring to her talent agency, is disputed and likely false, there is circumstantial evidence that makes the dox appear likely to have been undertaken by GamerGate's opposition or by third parties.

Gave positive coverage to Nina Freeman in two articles, without disclosing their friendship.

First to publish the false Brad Wardell accusations with the original one-sided article that started the scandal and was eventually thoroughly debunked.

Accused Twisted Metal creator David Scott Jaffe of being a misogynist for a juvenile joke during an interview. Slightly adjusted her position in a followup article.

Wrote about Iron Galaxy studios and their game Divekick without disclosing his personal relationship with the studio's David Lang — defined as "friendly" by Lang himself.

Article about Kickstarter's recent trend of being used for partial rather than full funding of games, whose original a headline accusing projects of "Lying about game budgets", implied to be talking about the Yooka-Laylee Kickstarter. Article was promptly amended, with Klepek admitting the mistake.

His article on X-Men Destiny used only the opinions of anonymous unverifiable sources with no independent proof or factual data to back the heavy allegations toward Silicon Knighs and their manager Denis Dyack. The allegations in the article were later denied by Dyack who offered his explanation for the issues that prompted the article.

Wrote about Aevee Bee, without disclosing that he was supporting her on Patreon—a support that might be ongoing since 2014, and is against the policies of Kotaku, where the article appeared. Disclosure was added sometime after the article’s publication.
