There was a keyboard I really wanted but it was no longer being made. However, I found an online shop that had them in stock! I ordered, paid, got my confirmation, and waited about two weeks before complaining that it hadn’t shipped.
Ended up with some dude from the usual geography for this stuff, yelling at me and threatening me over the phone. At which point I realized it was all fake, told him where to stick it and hung up. It was only $100 or so and I was lucky they didn’t do anything creative with my credit card.
The point being, there are lots of circumstances that can make you let your guard down. Thinking you’re too smart to be at risk is probably not the safest position to take.
