While China is hosting the most spammer websites, the United States continues to be the point of origin for the dissemination of spam, sending 60.5% of spam. The fact that 71% of spammers websites are hosted in China and 60.5% of the global spam is sent from the United States demonstrates that spam is a global problem and that spam is being sent from one country while another country is used as a hosted website to 'close the loop' of the spam transaction.
