Kari Ferrell became known as “The Hipster Grifter” after her cons went viral. In this episode of The Hidden Third, Kari joins me to talk about how her scams worked — from bad checks to stealing from friends and lying about being a cancer survivor — and how things escalated after she moved from Salt Lake City to New York City, where she landed a job at VICE.
We dig into what was driving her at the time, how easy it can be to manipulate trust, and what it’s like to become a public villain on the early internet.

In this episode, I sit down with MS NOW correspondent and bestselling author Jacob Soboroff for a candid conversation about what it takes to report on the stories that shape our country, and the personal cost that comes with it.
Jacob shares why he became a journalist, the biggest lessons he's learned in the field, the toll his work has had on his family, and even some secrets he's never divulged publicly.
We talk about his groundbreaking reporting on the Trump administration's family separation policy – what he saw firsthand inside migrant child detention facilities and what went into writing his book Separated. Jacob reveals what has stayed with him long after the headlines moved on, and warns that families are being separated at an even bigger scale during the current immigration raids.
Then we dive into his latest bestseller Firestorm, his firsthand account of the devastating January 2025 Los Angeles wildfires. Jacob reported live as his childhood home in the Pacific Palisades burned to the ground. He describes these fires as "the fire of the future" – not an isolated tragedy but a harbinger of America's new age of disaster driven by climate change, failing infrastructure, and political dysfunction.
If you care about journalism, immigration, climate disasters, and the human stories behind the headlines, this conversation goes deep.
