The question we now ask is whether or not we are seeing an increased amount of spam from those services.

The United States was number 1, followed by China. This is in terms of total volume of spam that they send. However, a second piece of data that I did not take a look at was where all of the individual spam sites contained within the spam was located. For example, does a lot of spam sent from the United States point to spammy URLs hosted in China?

In spite of its status of being a former Soviet republic, it relies on the internet for a substantial portion of everyday life -- communications, financial transactions, news, shopping and restaurant reservations all use the Internet. Indeed, in 2000, the Estonian government declared Internet access a basic human right...
