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.

After a California jury found Meta and YouTube liable in a landmark social media addiction case, we explain why the platforms you use may soon be unrecognisable. Plus - an exclusive interview with an expert witness from the trial, the world-leading addiction psychiatrist Anna Lembke, about how tech companies used persuasive design techniques found in gambling to keep us hooked online. 

Also on this episode, after Instagram and OnlyFans removed the accounts of the so-called 'Maga dream girl', Matt and Marianna discuss the world of AI influencers. As an increasing number of virtual creators amass millions of followers, is this becoming a medium for political propaganda? And do regular users care if they are real or not?

How has an algorithmic arms race created an environment where controversial and incendiary content is routinely amplified on our feeds? On this episode, Marianna discusses her latest investigation, which provides a paper trail showing how social media giants ignored internal warnings about the design of their platforms. She's heard from whistleblowers about problematic moderation practices, how companies deal with so-called borderline content, and the troubling reality that algorithms may now be beyond our control.

Also this week, we look at the website 'your ai slop bores me' which launched two weeks ago and is already claiming over a million unique visitors. It may look like a chatbot, but this is actually humans cosplaying as generative AI and completing mundane tasks for one another. Matt explains how this relates to what's becoming known as the 'meat layer', where humans are used to prop up the shortcomings of artificial intelligence.

Plus, how did a satirical post about a man being kidnapped by dolphins inspire a whole ecosystem of memes? And can you really make a million dollars online by selling ad space on your toilet seat?

Almost six weeks since the disappearance of Nancy Guthrie (the 84-year-old mother of Today show host, Savannah Guthrie) the case which has shocked America remains unsolved. It's also led to a host of online amateur sleuths broadcasting their own investigations to a mass audience on TikTok, with many descending on Guthrie's home in Tucson, Arizona. Marianna has reached out to some of the people posting to discuss their motives, the issue of misinformation and the risk of undermining an active investigation. 

And, as TikTok montages from the official account of UK Prime Minister Sir Keir Starmer attract criticism and ridicule, why do established politicians often struggle to thrive on the platform? Matt has been getting the perspective of the strategists behind some of the most successful political campaigns on social media.

A series of posts appearing to encourage violence between neighbouring UK schools has caused widespread moral panic, and prompted police forces to issue dispersal orders. But, with zero incidents reported, could the 'red vs blue' phenomenon be a phantom trend? Matt and Marianna discuss the knowledge gap between parents and younger people on social media, and how online frenzies can have dangerous real-world consequences.

Also, has Iran's retaliation to days of US-Israeli strikes exposed the reality of Dubai's flourishing influencer economy? As people in the UAE shelter from the threat of drones, content creators have been warned by the Emirati government about what they choose to share.

And, one of the world's biggest football journalists, Fabrizio Romano, is attracting criticism for a paid advert endorsing Saudi Arabia's humanitarian aid agency.

Over the past year, prediction markets like Kalshi and Polymarket have exploded in popularity, as users bet on everything from battles in Ukraine to sex toys being thrown at sports games. So with concerns over both regulation and the prevalence of insider information inviting intense scrutiny, Matt has been examining how these platforms really work.

Also on this episode, is the recent rise in measles cases in London down to disinformation? With several proponents of vaccine scepticism being welcomed back to social media, Marianna explains how these often discredited accounts are being amplified online.

And, as the viral story of Punch the monkey and his orangutan companion drives mass sales of an Ikea soft toy, we consider how brands are increasingly looking to profit from organic content through 'trendjacking'.

If your feed has been flooded with content about the 'dangers' of western cities like London or San Francisco, you're not alone - it's part of a growing phenomenon known as decline porn, and it's driving narratives of political neglect and uncontrolled immigration.

On this episode, Marianna examines a niche take on this trend - AI videos which falsely portray zoos and waterparks in Croydon. She tracks down the original creator of these posts, and explains why they might not be as innocent as they seem.

Also, Matt has been investigating Clavicular - the internet's man of the moment. After signing up to his 'looksmaxxing' course, we discuss the controversial relationships propping up his virality, and what the mainstream media is getting wrong about the streaming sensation.

In this brand new weekly show, BBC correspondent Marianna Spring and investigative journalist Matt Shea talk through the stories behind your social media feed. From global events that go viral, to bizarre moments that spill into real life, Marianna and Matt unpack the trends, theories and digital chaos shaping our world.

Can Coroners' courts cope with conspiracy?

It’s been more than a year since Paloma Shemirani died after rejecting chemotherapy in favour of alternative methods. Her brother Gabriel blames the beliefs of their mum Kate - who is a prominent British conspiracy theorist - for his sister’s death. This summer, he’s found himself face to face with his mum for the first time since Paloma died at an inquest into how and why she lost her life. After investigating - and revealing - what happened to Paloma for the first time almost four months ago, the BBC’s social media investigations correspondent Marianna Spring is back following the twists and turns of an inquest that has felt like Conspiracyland colliding with the real world. In the coroner’s court she see’s medics questioned by conspiracy theorists and tense family feuds unfolding in real-time. Could Paloma have been saved? And can society handle Conspiracyland?

Can people fight back against medical misinformation? In the months after Paloma’s death, her brothers say they want to prevent other deaths, and they believe social media companies should take stronger action against medical misinformation. Meanwhile her Mum, Kate Shemirani, takes to social media to share a different account of her death. She has promoted a range of unproven theories on social media and podcasts about how Paloma was murdered by medical staff. The BBC has not seen evidence to support this. The BBC’s social media investigations correspondent Marianna Spring interrogates whether and how some politicians and social media companies are emboldening anti-medicine conspiracy theorists, and speaks to a former cancer surgeon and patient trying to bust cancer myths online.
