Overview

Grummz's Catfight Hentai Website refers to a report that Mike "Grummz" Kern, an outspoken anti-woke poster on X and a former video game team lead, has allegedly maintained a secret online persona of Debbi Chan, under whose guise he launched and managed catfight fetish websites foxyfighter.com and freecatfights.com, for which Grummz also commissioned and produced NSFW content. The investigation also highlighted multiple instances of Grummz allegedly embezzling funds and avoiding taxes to fund his personal interests. The leak surfaced in late March 2025 via a YouTube video investigating Grummz's past online activities.

Background

On March 26th, 2025, the Western Kabuki podcast wrote on X^[1] / Twitter that they "had a scoop" about Mike "Grummz" Kern, a well-known reactionary account promoting an anti-woke message in the gaming industry on social media. The post claimed that the podcast reached out to Kern and that he refused to comment.

On March 30th, 2025, the YouTube^[2] channel MLYP posted an exposé video titled "Goonernomicon: Grummz | Part 1" that investigated the past online activities by former video game producer and anti-woke activist Grummz, including his alleged involvement into production of catfight fetish content under online persona of "foxyfighter" and "Debbi Chan." The upload (shown below) garnered over 207,000 views in one day.

On the same day, an expose article titled "Grummz: Odious Pervert, Failed Pornographer," written by Johnny Amizich, was published on Culture Dumpster.^[3]

Also on March 30th, the Western Kabuki linked the video and a spreadsheet supposedly documenting the timeline of Grummz's online activity for the past three decades, both as himself and under the guise of his persona, on X.^[4][5] The post (shown below) garnered over 2.8 million views, 2,100 reposts and 27,000 likes in one day (shown below).

The leak purportedly established a connection between Mike "Grummz" Kern and the websites foxyfighter.com, registered by Kern in May 2001 and managed by "Debbi Chan," and freecatfights.com, registered in December 2001 by Kern and managed by "Debbi Chan," as well as a number of satellite websites, including russiancatfights.com and latinacatfights.com, both now defunct.

On the websites, Kern used the online persona of Debbi Chan to manage them and to commission and produce fetish content, including written stories, comics and, in the 2010s, catfight fetish videos starring adult film actresses.^[6][7]

Grummz sold freecatfights.com to a "John Femmefight" in 2010. Foxyfighter.com then became defunct in 2021, since redirecting to a domain sale site.

The investigation also listed multiple instances of Kern purportedly embezzling company funds and avoiding taxes, with the money allegedly spent to fund his lifestyle and personal interests.

Later that day, Grummz replied^[8] to the post, "How did you get the passwords?" later making another post^[9] addressing the leak in which he dismissed it without refuting the claims (shown below).

Online Reactions

Following the leak, Grummz's past involvement in the production and distribution of fetish content, combined with the factor of his mature age (Kern was 33 when foxyfighter.com was launched, 47 when he joined Gamergate and 57 in 2025), became a viral subject of jokes online.

For example, on March 30th, 2025, X^[10] user @NebsGoodTakes made a post that received over 1,000 reposts and 26,000 likes in one day (shown below).

Later on March 30th, 2025, X^[11] user @Samul_VanDerHal made a post in which they reacted to Grummz not denying the claims made by the investigation. The post (shown below) received over 520 reposts and 8,300 likes in one day.
