A few years ago, a Microsoft research paper attempted to answer the question, "Why Do Nigerian Scammers Say They are From Nigeria?". That is, why do scammers (even non-Nigerian ones) claim to be from Nigeria when "everyone" knows about that Nigerian prince scam (among others)?

It's a really good paper, but tl;dr: Nigerian scammers know Nigeria has a bad reputation, and they want everyone who knows that to delete their scam/spam emails. Because then that just leaves the people who don't know about the Nigerian scam. Even if that cuts out 99,999 out of 100,000 recipients...sending out 100,000 emails is pretty cheap compared to the payoff from just one gullible victim.

But sending out the emails isn't the main cost for a scammer. The way that the scam typically works is that, when the recipient responds to the scammer, the scammer has to lead them on a tale of woe and misery (and sometimes implied sexual favors). That takes time. As a scammer, you don't want to spend a few hours of your time with someone who will eventually respond with "Hey wait a fucking minute, you're not a prince!" after doing a Google search. Ideally, they want someone so out-of-touch that they don't even have relatives or friends to communicate with, someone who does have access to the Google and who might call out the scam.

tl:drtldr Scams don't care about looking like a scam because they're filtering for people who don't know what a scam is.

So next time you turn your nose up at a campaign that uses goofy-looking 3D renders, or obvious Photoshops, or casually touts violations of well-known laws of physics...remember that that creator might actually be smarter (and wealthier) than you...
