Scammers know that they waste no time, and it's an opportunity when they find a hole in someone to prey on. Those are smart; that's why the only usual victims are people who have no awareness of what the scammers are doing.
Thank you, Op, for the reminders you gave here on the subject you did. As long as you can triple the caution because those scammers suddenly appear when we don't expect it, at least if we are prepared and aware of the moves, they will not make us victims for sure.
