Same as others, received a robo-call today from the "IRS" saying that they have "issued a warrant on" my name, and this is the final notice!  (Oh no!).  Got the same call twice within an hour.  Wish there was some way to block these things.  I can see how a nasty call like this might frighten some, particularly the elderly, into sending money.  I hope these scammers get what they deserve, but most likely they will not.
