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?

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.Top Comment is hosted by Marianna Spring and Matt Shea.
