Gabbie Hanna vs Trisha Paytas: Sexual-Health Rumor, Friendship Dispute and 2026 Revival
The feud became public in November 2019 after Trisha Paytas accused Gabbie Hanna of telling Paytas's then-partner Jason Nash that Paytas had herpes. Hanna acknowledged warning Nash about an unverified rumor but defended the decision as an attempt to protect a friend. Paytas denied having herpes and accused Hanna of harassment and slander. The dispute quickly expanded to mutual acquaintance Gabi DeMartino, a blackmail accusation by Hanna and Paytas's threat to involve lawyers. Hanna deleted her posts and said she was moving on, but the conflict repeatedly returned. In 2020 Hanna publicly revealed that she had originally written the song Call Me Crazy for Paytas before their falling out. In early 2021 Paytas appeared on Hanna's Burnout podcast in an attempted reconciliation, but a major disagreement remained over whether the two had ever been friends and how their past interactions should be characterized. Paytas said the restart failed. In June 2021 Hanna released previously cut podcast footage, text messages and a series of Storytime videos arguing that Paytas had lied about their friendship and gaslit her. The materials showed more friendly interaction than a simple claim that they had barely ever communicated, but the subjective question of whether the relationship constituted a meaningful friendship remained disputed. Paytas continued discussing Hanna publicly. By September 2025 Paytas had softened considerably, saying she wished Hanna well and apologizing for past ill will. Hanna reopened the feud on February 13, 2026 by publishing the full uncut Burnout recording and launching a podcast episode titled Why Trisha Paytas Tried To Ruin My Life, in which she accused Paytas of helping drive a long-term smear campaign and harming her career. No comparably detailed direct Paytas response to Hanna's February 2026 revival was identified in the reviewed material through August 30, 2026.
Trisha Paytas vs Ethan Klein: Frenemies Fallout, Production Dispute and Family Breakdown
The relationship between Trisha Paytas and Ethan Klein moved from a 2019 public feud to a successful collaborative podcast and then to a prolonged breakup. Their original dispute began when Klein mocked Paytas's edited photos in Instagram vs Reality and Paytas accused him of harmful body-shaming. Direct H3 appearances eventually turned the antagonism into a working relationship. Paytas then began dating Hila Klein's brother Moses Hacmon, creating a family connection. Frenemies launched in September 2020 and became highly successful, but the show repeatedly featured serious on-air arguments. The final regular episode, Frenemies #39, ended in a dispute about creative control, staffing, production ownership and a five-percent production allocation. Paytas announced a departure, while Klein disputed Paytas's account of the business and crew conflict. The following weeks produced multiple response videos, tweets and selectively released private messages. Paytas later apologized, but the friendship was not restored. A later Frenemies conversation was recorded and never released. The professional split expanded into a wider family estrangement involving Ethan, Hila, Moses and Paytas. H3 continued to reference Paytas in later years, including several 2024 and 2026 episodes, but no verified restoration of the friendship or Frenemies partnership was identified through August 2026.
Ethan and Hila Klein vs Matt Hoss: Copyright Claim, Fair Use Lawsuit and Court Victory
The conflict began after Ethan and Hila Klein published The Big, The BOLD, The Beautiful on February 15, 2016, a nearly fourteen-minute reaction and criticism video about Matt Hosseinzadeh's 2013 skit Bold Guy vs Parkour Girl. Hosseinzadeh threatened legal action, submitted a DMCA takedown notice on April 23, 2016 and filed a federal copyright action three days later after the Kleins challenged the takedown. The Kleins publicly announced the lawsuit in We're Being Sued on May 24, prompting a Philip DeFranco defense fundraiser that ultimately recorded $170,765 and the creation of the Fair Use Protection Account. Hosseinzadeh later added DMCA misrepresentation and defamation claims and publicly defended his lawsuit. On August 23, 2017, Judge Katherine B. Forrest granted summary judgment to Ethan and Hila on all claims, holding that their specific reaction video was fair use, dismissing the counter-notice claim and ruling that the challenged lawsuit commentary was either protected opinion or substantially true. The court explicitly cautioned that it was not declaring all reaction videos fair use. Hosseinzadeh's attorney criticized the result, but no later reversal was identified. The case continued to be cited in later commentary about online reaction content, including KQED in August 2026.
Ethan Klein / H3H3 vs Keemstar: Content Nuke, Sponsor Fallout and Long-Running YouTube Feud
The Ethan Klein-Keemstar feud developed over several years rather than beginning with Content Nuke. Keemstar was reported among creators who supported the Kleins' legal defense fund in 2016 and appeared as an H3 Podcast guest in 2017. The first clear public rupture followed the September 2017 PewDiePie controversy, when Ethan attacked Keemstar and Scarce during a drunken podcast rant and later apologized. Keemstar renewed criticism in 2018. The conflict escalated dramatically in April and May 2020 after Keemstar raised allegations about H3's Fair Use Protection Account and PAYDAY 2 DLC revenue. Ethan answered with Content Nuke, accusing Keemstar of a long pattern of false accusations, harassment, doxxing and harmful treatment of other creators, including discussion of Keemstar's past interactions with Etika. Keemstar disputed the framing, accused Ethan of removing context and hypocrisy, and issued two major response videos. The dispute then expanded into sponsor pressure, with Keemstar's G Fuel relationship ending and Old Spice reportedly ending its H3 sponsorship amid retaliatory campaigns. Later stages included Keemstar threatening legal action in 2020, H3 receiving a YouTube harassment-policy strike after mocking Keemstar's relationship age gap in 2021, continued podcast attacks and counter-attacks, and disputes involving Teddy Fresh in 2022. H3 continued discussing Keemstar in later content through at least 2025. No public material reviewed establishes that Keemstar caused Etika's death, and no filed Keemstar-versus-Klein lawsuit was identified from the 2020 threat.
Ethan Klein vs HasanAbi: fallout and reaction-stream lawsuits
After Leftovers collapsed over Israel-Gaza disagreements, Ethan Klein and Hasan Piker escalated into public accusations, Content Nuke and a direct debate. Klein's company then sued Denims, Frogan and Kaceytron over reaction streams, producing a settlement, a default dispute and a fair-use win for Denims.
