Someone calls and says, “Grandma, i’ve been in an accident …” and so on. Why don’t people ask a few questions? If you’re my grand daughter, what’s my name, when is my birthday, where do I live, what’s my favorite food?

        here’s one. it’s a paper from microsoft research researching why so many scammers say they are from nigeria, but the same premise applies:

        Far-fetched tales of West African riches strike most as comical. Our analysis suggests that is an advantage to the attacker, not a disadvantage. Since his attack has a low density of victims the Nigerian scammer has an over-riding need to reduce false positives. By sending an email that repels all but the most gullible the scammer gets the most promising marks to self-select, and tilts the true to false positive ratio in his favor.

          That was an interesting read - and indeed a citation. Thank you.

          However, there are one serious and one minor flaw in their arguments:

          That the collection point for the money is constrained to be in Nigeria doesn’t seem a plausible reason either. If the scam goes well, and the user is willing to send money, a collection point outside of Nigeria is surely not a problem if the amount is large enough.

          That is simply an unproven assumption, and a wrong one at that. And it leads me to doubt the depth of that persons knowledge of Nigerian scams.

          While scammers from Nigeria do have methods to collect money that victims have sent to another country (through accomplices or unwitting mules), those come with additional costs and risks. And that is usually not worth it in the initial stages of the scam, when the amount is not „large enough“, usually a few hundred, maybe thousand dollars. Only when the victim is „committed“ by sending a small amount do they usually increase their demands, and then it is of course worth it to produce eg a bank account or even offer a meeting in the west.

          As a side note: there has been a bit of a shift in Nigerian scamming over the last few years. Scammers seem to move from the „traditional“ advance fee fraud over to romance scamming, which they often do under a „western“ false identity, and for which they prefer gift cards and bitcoin as payment. It would be interesting to see if that is more than correlation.

          Only when potential victims respond does the labor-intensive and costly effort of following up by email (and sometimes phone) begin.

          While this is not entirely false, it is inaccurate. Scammers usually have at least the first few emails prepared, so the first few replies (in which they explain a bit more) are nothing more than copy and paste - not exactly „costly effort“. Quite often those first emails also include small tasks for the victim, like sending their passport scan, filling in forms or actively contacting someone else by email, which is an actual filter.

          So you see, it’s a bit more complex than that meme „they are preselecting stupid people“.

            interesting conclusion, maybe you should publish? you seem to have more info than they did ten years ago.
