my dad (80 YO) has a PhD in computer science and has been scammed multiple times. I have had multiple employees buy about 7K in gift cards for scammers. I personally bought a $200 electric surfboard that ended up being a $20 boogie board (facebook ad). I immediately realized it was a scam but paypal wouldnt let me cancel the transaction. They said I had to receive the item first. Then when I received the item the refund link wouldnt work (errored out). I ended up just giving up and eating the $200. A retired friend had all bank accounts and investment accounts drained (millions). Im not sure how this happened, but 2FA is a must for big accounts. Im pretty sure scammers make a lot of money. These days I mainly get car warranty calls.
