Spam is a world wide problem and is unlikely to get easier. There are two important points. First, the vast majority of spam does NOT originate in China. Most of it is from the United States. The second is that it is very easy for the individual user to control spam so that it ceases to be a nuisance.
For some of us the problem of spam is pretty nigh non-existant. Using a program like Google’s Gmail it can be set up quite easily so that most spam is filtered out into a special holding basket where it does not interfere with normal mail and can deleted in bulk. Most mail programs allow this so spam proofing is relatively easy.
Finland, Canada and Belgium rank in the top three in terms of anti-spam security, whereas China, Azerbaijan, and South Korea rank worst.
There is a great myth that most spam originates in China. It does not. Spam from botnet computers (computers that have been taken over by malignant forces without the users knowledge) rarely indicate where the spammers really reside.
In the creation of spam the US ranks first, followed by Spain and the Netherlands.
Note the US press, especially the computer press, tries very hard to cast China as the villain in this and disguise the fact that the majority of spam originates in the United States.
InfoSecurity reported that different types of spam campaign used harvested messages with varying speed. The result is still the same. Spam comes to you computer. It is a problem but a containable problem for anyone who uses ordinary care when accessing the internet.
