According to The Register, two thirds of the world’s spam is sent by Taiwanese servers:

Almost two thirds (64 per cent) of servers controlling spam traffic are located in Taiwan, according to a survey by email security firm CipherTrust.

Such servers, used by internet low lives to relay spam and phishing emails through zombie, compromised PCs, are also commonly located in the US. The US accounts for 23 per cent of the machines identified on CipherTrust’s spam server blacklist with China in a fairly distant third place (three per cent).

That’s right. We’re not only number one, but we’re dominating. No wonder my email always used to get blocked when I sent stuff from my Seednet account.
