Got a robot call from this number saying it's the irs and that they are filing a lawsuit against me and that I need to call them asap, which I did. A guy with a VERY foreign accent answered and identified himself as Peter Anderson, an employee of the irs. I asked what this is about. He asked me to tell him my first and last name. I responded by telling him I'm blocking his number so don't bother calling me again. Then I hung up.
