Yes this is comon practice these days. Digital criminals going after older people who may be gullible or not tech savy at all or just be senile or what not. I mean it's in the news all the times
I was in my 30's before cell phones and home computers became a thing. I remember when the only email available to most people was AOL. Plenty of older people are overwhelmed with all the tech and pass words. They have multiple bank pass words, medicare, social security and plenty of billing with computers. It's easy for someone to call trying to con an old person who is buried with trying to figure out tech crap.
I remember in the 80's when computers were brand new in terms of use and businesses began to use them. Guys that went to school for computers were making a sick amount of money because people had a ton of trouble trying to figure them out for their businesses. Companies were throwing money at them. On guy I worked with told me he owned two houses and two really nice cars. Then when computers were common place he was reduced to being a low paid IT person.
A friend said he asked his adult son with a computer question and his son was annoyed saying this is basic stuff. The adult son started on computers when he was five. My friend told him, "I taught you how to eat with a spoon, it's the least you can do to help me with this problem."
