Who scams the scammers? Meet the scambaiters

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.
