Top Comment

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.
