I was so, so glad my Grandpa never got online. Not only did he develop dementia, he actually lived in Nigeria for some years, and made quite a lot of money on the stock market, so he was the person friends came to for financial advice… Including some from Nigeria. Scammers couldn’t have designed a better victim.
He just got old school scammed by some guys who ‘fixed his roof’ without even going up the ladder. They got a few thousand, but at least the neighbours twigged and called my Aunt, who got some form of financial guardianship in place, so he couldn’t take thousands out of the bank without them checking with her.
