Why is so much spam so obviously bogus? asks a recent BBC article. We have all gotten emails from a Nigerian finance minister offering to share stolen funds with us. The email is full of misspellings, and even the source of Nigeria is a tip-off. Who falls for this stuff?
The article points out that this crude approach is part of the strategy. Only the most gullible of the gullible are taken in, so the perps do not have to waste their time with others who will not follow through. Make the message too convincing and they will get too many false hits—those who will balk at sending their bank account and social security numbers in the next step. Keep it crude and the few most promising marks will self-select.
