It's not easy to say what Oli Frost does, but it's marginally easier to name a few of the things he has done. He's the guy who put all his personal data on eBay, played recorder for Simon Cowell, and started a service to help you fake a perfect online life.
But in the last few years, Oli Frost has turned his attention to a new mission: refrosting our defrosting planet. His plans to date have included impersonating his local council's recycling department, writing a song for Greta Thunberg, and starting a climate strike for baby penguins.
