Who scams the scammers? Meet the scambaiters

Police struggle to catch online fraudsters, often operating from overseas, but now a new breed of amateurs are taking matters into their own hands

Three to four days a week, for one or two hours at a time, Rosie Okumura, 35, telephones thieves and messes with their minds. For the past two years, the LA-based voice actor has run a sort of reverse call centre, deliberately ringing the people most of us hang up on - scammers who pose as tax agencies or tech-support companies or inform you that you've recently been in a car accident you somehow don't recall. When Okumura gets a scammer on the line, she will pretend to be an old lady, or a six-year-old girl, or do an uncanny impression of Apple's virtual assistant Siri. Once, she successfully fooled a fake customer service representative into believing that she was Britney Spears. I waste their time," she explains, and now they're not stealing from someone's grandma."

Okumura is a scambaiter" - a type of vigilante who disrupts, exposes or even scams the world's scammers. While scambaiting has a troubled 20-year online history, with early forum users employing extreme, often racist, humiliation tactics, a new breed of scambaiters are taking over TikTok and YouTube. Okumura has more than 1.5 million followers across both video platforms, where she likes to keep things funny and light".
