Spam Cop

SpamCop is a spam reporting service, allowing recipients of unsolicited bulk email (UBE) and unsolicited commercial email (UCE) to report IP addresses found by SpamCop's analysis to be senders of the spam to the abuse reporting addresses of those IP addresses. SpamCop uses these reports to compile a list of computers sending spam called the "SpamCop Blocking List" (SCBL) or "SpamCop Blacklist."
