If you're like me, you get frequent calls from scammers based in India pretending to be from the IRS. They threaten to come to my house or place of work to arrest and jail me unless I pay them alleged back taxes in the form of gift cards(!). They are laughably bad at trying to con money (see my post "An IRS scammer called me and I made him mad"), but they do well with seniors and immigrants.
According to an article on Vox, "IRS Inspector General Russell George said his department heard from about 2 million people who said they received these calls — about 10,000 of whom admitted to paying the scammers, to a tune of about $50 million. And that's just the people who contacted them."
In order for these scams to work, the Indian scammers need to employ criminals in the US to deal with the gift cards. On Thursday 20 people in the US were arrested for allegedly participating in a fake IRS ring.
