New study about spam blames US as source of spam

We have to take care with the numbers in this report since they come from a firm called Sophos (http://www.sophos.com) that promotes anti-virus and anti-spam software. But the numbers from their research put an interesting spin to existing perceptions, as they are saying that about 42.53% of all spam actually originates from the US, followed by South Korea (15.42%), and China and Hong Kong (taking a total of 11.62%).

They provide some more numbers for other countries, called "the dirty dozen". These include Brazil (6.17%), Canada (2.19%), Japan(2.87%), Germany (1.28%), France (1.24%), Spain (1.16%), Britain (1.15%), Mexico (0.98%), and Taiwan (0.91%).

It is quite difficult to believe that countries such as China, are that far down the list, actually. Remember, they were earlier accused of being one or the major source of spam. It is also not clear from the article, if the numbers include those spam messages that were fired from so called zombie computers.
