Due to my father's browser sloppiness, and in spite of my efforts to NOT see what he's doing, I know he is on dating sites talking to women. I was fixing something for him when a chat window popped up, which I minimized right away without looking at it, but I saw enough to know it was sexually suggestive, and when I typed to search for something in his search bar the first things that came up after one or two letters was the name of a dating site.
He is 75 years old and in declining health, and he looks after my mother who is no longer able to care for herself, so I chalk this up to just fantasy and it's none of my business. He spends most of his free time on the computer, apparently just playing solitaire, but I'm pretty sure that's just what he wants me to see.
Also, he recently tried to sell something on Craigslist and was taken for $2000 in a certified check scam.
So all of this leaves me worried he may be vulnerable to being catfished, and could lose catastrophic sums of money (they have modest retirement savings.)
How to warn him about this without embarrassing him, or making it look like I'm judging him or that I snooped? (I didn't!!)
