Microsoft has done some research on of all things, the reason why Nigerian scammers always claim to be Nigerian royalty caught in outlandishly ridiculous situations.
There’s a lot to read here if you’re into that sort of thing, but the main takeaway seems to be this.
The key here is reducing “false positives.” Basically, scammers don’t want to waste time with semi-competent people. They only want the dumbest of the dumb to fall into their web for an overall smoother operation.
Obvious I know, but I’m just happy to see some officialish evidence to back up what a lot of us have been saying forever.
