Why you're wrong about Palantir, and TL;DR Tolkien

Agartha explained, and hot girls revolt on BookTok

The BookTok community has erupted after creator AllieRoseCo announced she had trademarked merchandise featuring the phrase 'Hot Girls Read'. User backlash was instantaneous, with many accusing her of attacking small businesses and even betraying her own followers. On this episode, Marianna explains why BookTok is such an influential marketing demographic on TikTok, and what this controversy tells us about the fragility of influencer careers tied exclusively to a personal brand. Also this week, a viral photo which appears to show Donald Trump meeting with a group of mysterious figures has led to a raft of theories about their identities. One of the most prominent narratives to emerge is that the men are representatives of the mythical kingdom Agartha. Matt dives deep into the lore on Agartha, and its adoption by Nazi occultists. Why has this theory seen such a resurgence among young people on TikTok, and how dangerous is the implicit ideology behind it? Top Comment is hosted by Marianna Spring and Matt Shea.

Belfast, Henry Nowak, and how Grok is supercharging misinfo

After a second night of rioting in Belfast, social media companies are being accused of playing a role in creating disorder. Technology secretary Liz Kendall has said an update to the Online Safety Act will be brought to parliament next week, putting greater pressure on platforms to remove content which seeks to incite violence. On this episode, we explain why X is receiving particular scrutiny, and how its integrated AI chatbot Grok has fuelled misinformation surrounding cases from the murder of Henry Nowak to the deadly Bondi Beach shooting. Also this week, with the UK government reportedly poised to announce significant restrictions for young people using social media, Matt and Marianna discuss how we got here. They examine some of the arguments for and against limits for under-16s, and ask whether a de facto ban could be reversible if companies address safety concerns. Plus, another platform monetising dares, and the return of fake BBC crypto ads. Top Comment is hosted by Marianna Spring and Matt Shea. The series producer is Laurie Kalus.

Is Hasan Piker NSFW now? And Tung Tung's generational run

When Twitch streamer Hasan Piker was denied entry into the UK this week, it rekindled a conversation around the Home Office's approach to free speech. From Kanye West to Valentina Gomez, the list of prominent names who have seen their travel plans derailed in recent months is growing, with commentators across the political spectrum accusing the government of overreaching. Piker, whose highly critical stance on Israel has led to disputed allegations of antisemitism, says he is being targeted for his position on the war in Gaza. On this episode, Matt and Marianna explain why many young people in particular are outraged by the decision, and consider whether some of his more inflammatory comments should be considered less extreme in the amplified environment of social media. Also this week, the police officers who were falsely identified in the aftermath of Henry Nowak's murder. And, how Tung Tung Tung Sahur's recent resurgence has secured his crown as the undisputed king of brainrot. Top Comment is hosted by Marianna Spring and Matt Shea.

Sleuth wars, incels in STEM, and just want Harambe back

An inquest is set to open on Friday into the deaths of three sisters whose bodies were recovered from the sea off the coast of Brighton. The case has led to rampant speculation online, particularly after it emerged that a widely shared image provided by family members appeared to be AI-generated. From unfounded conspiracies about serial killers, to a broader debate over the handling of cases involving black people, it has captivated TikTok sleuths, some of whom are even turning on each other. Also this week - a decade on from his death, Matt and Marianna remember Harambe, the gorilla who achieved internet immortality. Plus, an intriguing job ad from a virtual relationship site, and the Fox News interview being reposted over false claims that a featured contributor was wearing a prosthetic mask.

Why you're wrong about Palantir, and TL;DR Tolkien

The US tech giant Palantir holds contracts with some of the most influential entities in the world, from government departments and pharmaceutical companies to military contractors and banking powerhouses. Funding links to the CIA, misconceptions about how it operates, and broader concerns surrounding the use of private data, have all led to a significant protest movement online at the firm's increasing integration into major institutions. On this episode, Matt and Marianna consider why a narrative framing Palantir as a malevolent force is flourishing on social media, and ask whether this stealthy reputation actually suits its business model. Also this week, after a former Meta AI researcher told the BBC that smart glasses are "an invasion of privacy", is being filmed covertly for content a new reality of everyday life?
