Couldn't you just imagine some people getting very scared and paying up?
It's horrible when I think of it tbh.
I think of my old dad who was sharp as a tack until he reached his mid 70s, if one of these scammers called him back then I could totally see him believing it.
I had a friend in the US who fell for this a few years ago - she was in her 30s at the time. When she told me the story, she was really embarrassed because she ended up paying them over $3,000 - it had all the classic hallmarks of a scam, threatening the police, being on the phone for hours to her, telling her to go to CVS and buy visa and Mastercard gift cards and read out the numbers to them.
I couldn’t believe she had fallen for it, but she said the phone call started legit, they sounded like they knew her situation and she was afraid of getting into trouble with the IRS. They kept on to her for hours and in the end, she paid up because she was so frightened. She knew after that it was a scam and reported the episode to the police but they couldn’t do anything and just advised her not to pay out again, they’d never come for her at her house for tax issues like the scammers said.
You’d be surprised how many people fall for things like this and then don’t share because they are embarrassed to have been fooled.
