Spam's U.S. Roots
ahab_2001 writes "Notwithstanding how tired my finger is getting from deleting all of those unsolicited messages from China and Korea, Information Week reports that a study of filtered messages by the spam-blocking firm CipherTrust revealed that some 86% of spam originates in the U.S. Apparently, a very limited set of IPs with high-bandwidth connections is dishing out the bulk of the spam, according to this study."
... and ugly websites!
...ooops, check 'Grammar' above
Another way to phrase the article title could have been 'Spam has its roots in US'. Replace the word root with 'origin' and the meaning becomes more clear (hopefully).
If you look at this definition you can see that the fifth entry uses the term 'primary source'. In this case the primary source of spam is the US.
Hope this helps.
P.S. Considering English is not your first language you write much better than a large percentage of people on this board who were born in the US.
