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.

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?

On this bonus interview episode, Matt and Marianna are joined in the studio by leading social media journalist Taylor Lorenz. They discuss the evolution of meme culture, Clavicular's enduring virality, and why Elon Musk briefly kicked her off X. Plus, as the list of countries seeking stricter regulation of social media grows, why is Taylor so resistant to the legislation being proposed in the UK and US, and what are the alternatives?

Foreign-based social media accounts are masquerading as patriotic Brits lamenting the UK's 'decline'. These profiles, which use AI to amplify anti-immigrant rhetoric, are being viewed and shared by vast audiences who are often unaware of the content's origin. The BBC has seen evidence that dozens of those posting from Eastern Europe to South Asia are coordinating their activity through group chats, with some even claiming to be in communication with political actors inside the UK. Marianna and Matt discuss the ideological approach of these remote creators, and explain why their tactics are reminiscent of modern state-backed influence campaigns.

Also this week, the TikTok users reclaiming fruit from AI, and why Charli XCX's latest promo campaign is splitting opinion.

Launched last year, the website Dare Market describes itself as "the platform where you can dare anyone to do almost anything for real cash bounties". On this episode, Marianna speaks to Isla Rose Perfito, the founder of the site inviting comparisons to Black Mirror. From the individuals putting themselves at risk for financial gain, to brands sponsoring increasingly outlandish challenges, we ask whether her vision of a flourishing attention economy which rewards small entrepreneurial creators is realistic. And, why did the Church of Scientology send her a cease and desist letter?

Also this week, a viral interview from SXSW has reignited online discourse surrounding music's so-called 'industry plants'. Revelations about fake influencer campaigns are calling into question the rapid rise of bands and artists like Geese and Oklou, who were once celebrated for growing loyal audiences independently. In an online ecosystem dominated by digital marketing, Matt considers whether the concept of discovering new music organically is now an illusion.

Plus - panic over hantavirus, and the wild JPMorgan lawsuit sending meme production into overdrive.

Following an apparent assassination attempt at the White House Correspondents' Association dinner on Saturday night, dozens of high-profile conservative accounts posted almost identical reactions on X. On this episode, Matt and Marianna explain why some people think these posts are coordinated, and debunk false claims the event itself was staged.

Also this week, why are conspiracy theories surrounding the tick-borne infection Lyme disease receiving so much online attention? And, the AI songs TikTok users are creating with texts from their ex.

Haley Beck - the sister of influencer Noah Beck - has denied wrongdoing after police recommended she be charged over allegations she cultivated a sexual relationship with a student in Arizona. The case is receiving outsized attention on TikTok, from testimonies by the teacher's former students, to those dissecting the thousands of messages she exchanged with the alleged victim. As details from a police report dubbed the 'Beckstein files' continue to circulate, Marianna and Matt consider what this coverage means for the rights of those at the centre of the case, and the integrity of any potential prosecution.

Also this week, we're looking at the highly convincing fake BBC news articles being promoted on Truth social and other major sites. One example, which describes a fictional altercation on Question Time between Nigel Farage and the governor of the Bank of England, appears to be an elaborate attempt to promote a murky crypto operation.

Ahead of Coachella's second weekend, Matt and Marianna are discussing how the festival often referred to as the 'Influencer Olympics' has become a microcosm of creator culture. They chat about people posting from their hotels without ever entering the event, the TikTokers mourning collapsed brand deals which may never have existed, and the AI influencers sharing their generated experiences in the desert.

Also this week, social media outrage appears to be fuelling protests over Surrey Police's response to the rape of a young woman by a group of men in Epsom. As online speculation grows about the racial identity of the suspects, how does this situation compare to more extreme examples of violence such as the Southport Riots?

Plus, as Johnny Somali is jailed in South Korea and Clavicular is hospitalised after an apparent overdose, we explain why streamers feel increasingly incentivised to take risks for their content.

Lego-inspired characters depicting conflict in the Middle East. This Iranian brand of so-called slopaganda has been viewed hundreds of millions of times and it is colouring the conversation around the US and Israel's war with Iran. On this episode, we speak to a key creator behind the content - the man who calls himself Mr Explosive - and challenge him on his connection to the Iranian government.

Also this week, will a TikToker running into the Church of Scientology's LA headquarters rekindle the trend of 'trespasser content'? And how Nutella are capitalising on the historic Artemis II space mission.

When newly-elected Green Party MP Hannah Spencer gave her maiden speech on International Women's Day, she was subject to a torrent of online abuse targeting her appearance, with one user on X prompting Grok to "smarten up" her look. The chatbot continues to be flooded with similar requests, despite a crackdown by the platform on 'undressing' content earlier this year. Marianna and Matt discuss how AI is supercharging misogyny online, and hear from Hannah Spencer about her experience.

Also on this episode, apparently it's a bad week to be a boomer (unless you're Kris Jenner). We chat about Paul McCartney's Reddit ban, the leaked photos exposing the private life of Kristi Noem's husband, and a crypto hoax wrongly announcing the death of a 194-year-old tortoise.

Plus, why an animatronic snowman is sending the internet into meltdown.
