Even knowledgeable people can fall victim to attacks like this.
The data on the page on Etherscan:
https://etherscan.io/address/0x29d7d1dd5b6f9c864d9db560d72a2...
does provide some insight at a quick analysis.
The total sent is (at the 494,170.68/1492=331.214 rate) almost exactly 500,000 US$ (499,821.59) of which, in four operation of 373 Eth each 1492 Eth were withdrawn 494,170.68.
Of the 212 total operation 4 are withdrawals, 3 are 0, that makes 205 "IN" operations.
The distribution of the amounts of the single operations/deposits is interesting, I quickly put together a few "classes":
a. >30,000 2 Total 66,243 US$
b. 20-30,000 3 Total 70,840 US$
c. 10-20,000 6 Total 82,803 US$
d. 5-10,000 14 Total 102,576 US$
e. 2.5-5,000 23 Total 80,125 US$
f. 1-2,500 33 Total 54,225 US$
g. 0-1,000 124 Total 43,010 US$
If the "targeted audience" was around 9,000, roughly 200 or 2.2% fell for the phishing.
A handful of people (classes a., b., c., 11 in total, i.e. coincidentally roughly the 0.1%) contributed for almost half the amount 66,243+70,840+82,803=219,886 219,886/500,000=43,98%.
If we look at the Nigerian '419' scam, apparently the emails are written in bad English to filter out the smarter people that are unlikely to fall for the scam anyway. The reason is that handling the response on such an email is labor intensive and the people behind those scams prefer to only use labor when chance of success is high.
