Accept that nothing you do will work short of legally assuming 100% control of her finances. I had a grandmother do exactly the same thing in the 1980s and 1990s via phone scams. She died penniless, having dithered away $X00,000s in cash and retirement assets. This behavior was extremely compulsive on her part and quite outside her ability to examine rationally or control - think gambling addiction rather than "stupid decisions." I think it is extrememly unlikely that any intervention by you and your family will help. Your mom is not able to stop and will not stop.
