The Register reports that China continues to be the world's primary source of spam Web sites--hosting the Web sites that show up in all that email spam. The U.S. continues to be the source of most email spam.
Why China if most spammers are in the United States? It's getting harder and harder to find a U.S. based Web hosting firm that wants the headaches associated with the complaints and problems associated with spam Web sites. China, half a world a way and run by a communist government that tends to turn a blind eye towards things like respecting copyrights and other niceties of the free world, is happy to take spammers' money for hosting the sites.
