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. The security firm performed an audit of its honeypots to come up with the figures ―a honeypot is a special system set up to attract spam or spammers in order to gauge spammer activity. 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. Yet these percentages still point to the U.S. as being a disproportionate source for spam.
The United States produces spam.
