ASPEWS is a list of areas on the Internet which several system administrators, ISP postmasters, and other service providers have assembled and use to deny email and in some cases, all network traffic from.
Most spam advisory and blocking systems work after the fact. There is a time lag between the spammer setting up shop, spamming millions, and getting netblocks listed by these systems. ASPEWS identifies known spammers and spam operations, listing them as soon as they start, sometimes even before they start spamming.
