Problem: Context: According to research done by an anti-spam research company Sophos, the United States is the point of origin of over 42% of all spam. Trailing are South Korea with 13% and China with 8% of the world's spam.

Such activity is not entirely unexpected. The United States accounts for slightly over 25% of all Internet usage, whereas South Korea and China have about 4% and 11% of the world's Internet users, respectively.
