Yikes, talk about getting pro-active on the SPAM front. This entire ISP's customer base, almost 1 million people, was blacklisted. Hope no one over there was expecting an important email anytime soon.... heh.

"The Spam Prevention Early Warning System (SPEWS), whose blacklist is referenced by many antispam controls, imposed the block in response to the high number of Telewest customers whose machines have become compromised and taken over for the purpose of sending spam."
