Way back in the mid-2000’s, I did constituent relations work for a congressman, and very early on we dealt with a constituent that had, over the course of about a year and a half, wired about ninety grand to a very blatantly obvious scam based out of Kenya and just couldn’t understand why he wasn’t getting his promised fortune from them. He kept claiming, without proof, that it was connected to a standing lawsuit he had filed years ago (but which a) hadn’t been won or settled and b) had nothing to do with anything in Africa). I kept telling him it was a scam, but he refused to believe it.
He eventually showed up with correspondences he had received over the previous few months on some some kind of colonial bank letterhead as if it was a gotcha of some kind. I did a literal five second Google search on our office desktop in front of him of just that bank name and showed him that it had closed back in the sixties along with a load of other such colonial institutions after the Brits pulled out.
Dude went from being positive he was getting a huge payday soonish to realizing he had lost a fortune to a scam in the span of a third of a second after that.
