They might claim to be from the IRS, insisting you have overdue payments and asking for your credit card information.

Your post is right on. There should be more steemiens reading this to get well informed. It actually happened to me. Phone call few years ago. This person pretended to be from IRS. He said few things that concerned me at the beginning, but as the conversation progressed I realized it was a scam. Of course I didn’t give him any info, but obviously I pissed him off that much, he even said to me that warrant was issued against me and there was nothing I could do. He said the police will come in a few minutes to arrest me. That day I was so pissed. I went to the police station and they said it’s mostly people from India. It even happened to few policeman I spoke to that day.
