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.

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.

What are cancer patients seeing on social media? The BBC’s social media investigations correspondent Marianna Spring goes down the cancer conspiracy rabbit hole to find out.

Could the answer lie in the past? The BBC’s social media investigations correspondent, Marianna Spring, continues investigating what happened to Paloma Shemirani. She speaks to Paloma’s brothers to see if the answers could lie in the house they grew up in. Who is Paloma’s mum - prominent British conspiracy theorist influencer Kate Shemirani - and how did her beliefs evolve and impact Paloma and her siblings? Could her mum’s conspiracy theory views have influenced Paloma’s decision to reject chemotherapy?
