SpamCop is an email spam reporting service, allowing recipients of unsolicited bulk or commercial email 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" or "SpamCop Blacklist".
History
SpamCop was founded by Julian Haight in 1998 as an individual effort. As the reporting service became more popular, staff were added and the SCBL became more useful. It has commonly been the target of DDoS attacks and lawsuits from organizations listed in the SCBL. Email security company IronPort Systems announced its acquisition of SpamCop on November 24, 2003, but it remained independently run by Julian Haight. A small staff and volunteer help in its forum. IronPort agreed to become a division of Cisco Systems on January 4, 2007, effectively making SpamCop a Cisco service. Julian Haight left approximately two years after the Cisco acquisition. SpamCop views itself as an attempt to stop spam without the necessity of governmental intervention, but because it lacks the power of a government or large ISP, it may have greater difficulty dealing with spammers' expertise as well as the large bot networks that they control and that they used to cripple Blue Security with a massive DDoS attack. SpamCop previously provided paid email accounts through Corporate Email Services. On August 9, 2014, in an email to email account holders, CES announced that "s of September 30, 2014 6pm ET, the current SpamCop Email service will be converted to email forwarding-only with spam filtered by SpamCop for all existing SpamCop Email users" and that "SpamCop will no longer provide IMAP or POP service ."
Benefits
SpamCop is effective at helping ISPs, web hosts and email providers identify accounts that are being abused and shut them down before the spammer finishes operations. SpamCop provides information from its reports to third parties who are also working to fight spam, amplifying the impact of its services beyond its own reach.
Limitations
For first-time SpamCop Reporters, the SpamCop Parsing and Reporting Service requires that the reporter manually verify that each submission is spam and that the destinations of the spam reports are correct. People who use tools to automatically report spam, who report email that is not spam, or report to the wrong people may be fined or banned. This verification requires extra time and effort. Despite these steps, reports to innocent bystanders do happen and ISPs may need to configure SpamCop to not send further reports if they do not want to see them again.
