The world’s second largest ISP, Savvis (who?) has at length agreed to kick 148 of the worst spammers off its network. It was initially reluctant to do so (one source claimed it earned $2m a month from hosting them) but a whistleblower went to the “Spamhaus”:http://www.spamhaus.org/ anti-spam organization who threatened to block access to all email from Savvis for everyone using their spam blocking software. Frankly I find this kind of quasi-blackmail morally dubious at best, but it does seem to have worked.
The BBC report ends, ‘as they are thrown off one service provider, there is always another one ready to take them on for the lucrative business they bring,’ but I am more sanguine. If spammers could be thrown off all the large, reputable ISPs and driven onto fringe players, they would be easier to find and their cost base would rise.
P.S. Interestingly (to me, anyway) Savvis inherited many of these offenders from its purchase of Cable and Wireless, a UK company I used to work for (on the digital TV not the ISP side).
