I hear you. Same with my dad. Found out after he gave his old phone to my mom without logging out. Tried to show him he was falling for MS-clipart certificates and bossofbigbank@gmail.com but to no avail.

After tracing 250k wired in just 6 months, we detangled my mom out of potential liability and reported him. He was put into financial stewardship (= personal finances done by an attorney). He appealed and the court ruled he seems normal, so he could also be in charge of his finances with only a monthly checkup. We still had his email access. He contacted his scammers the day after promising more money soon...

Fast forward to today, he's broke, likley evicted from his auctioned off appartment in a couple of months at age 79 and dividing his pension between wiring it to scammers and eating just enough to stay alive. Lost all his friends (many borrowed him money), doesn't see his wife or grandkids grow up. The opposite of a happy end.

If you find yourself in such a situation: - I received a lot of valueable advice from the local anonymous addiction hotline (how to react, where to seek help). Best call you can make. - In Switzerland, the KESB (govt authority for protection of elderly and children) can help you. They had a neurological assessment made and a court put him financial stewardship. It would have saved him from himself if not for his appeal. - Think ahead and have one person act as "bad guy" - everything I tried was in consensus with the whole family, but I played bad guy. Of course my dad broke with me, but he keeps sporadic contact with everyone else - his only social contacts - priceless.

I see legislation improve hereabouts - my bank (in France) now requires to watch a screen for 3 seconds and confirm you're sure to wire X to Y and you are sure Y is Y before oking a transaction. Far from enough. We infortunately won't convince our dads that they are getting scammed, but better consumer (and boomer) protection is something we can lobby and vote for.
