These people prey on the elderly and others who just don't realize what scams this is and that NONE of these sweeps are legit! I remember watching one of those news reports/investigations shows on TV where they were interviewing an adult daughter whose mother still continued to enter the sweeps even after losing friends, family ties, all her bank acct and savings gone! I had a client (I used to be a case manager for elderly) whose daughter contacted me so she and her sister could file for power of attorney and guardianship over their mother because of this same thing. They had to have her mail start going to a P.O. box which they set up so that they could screen her mail and stop the "sweeps" and "You just won " crap that of course she never entered. Only after the mail was not delivered directly to my client did it stop and they started to be able to get a grip on her blowing all her assets. You can't win if you didn't enter (Did your name. address, other personal info just fall out of the sky?) and if you send money overseas you can never get it back because American government/court systems have no jurisdictions in any other countries. What gets me even more is the one calling itself the Euro, Afro, Asian Lottery. WHY don't people who receive garbage from them ask themselves, "If its the Euro, Afro, Asian Lottery/Sweeps, then WHY are they telling people in the USA that they won?!"
Good luck with helping your mother and restoring your sanity once you can clean up the aftermath. She's lucky to have you. Many people don't have someone to step in, and some seniors hide it so well, many family, friends, caregivers have no idea its going on!
