SpamCop operates an anti-spam "blocklist" that can be used by third parties as a reference to block junk e-mails. The list is compiled by users informing SpamCop when they receive an unwanted e-mail. SpamCop then uses the information to determine the Internet Protocol (IP) addresses used to send the messages, and forwards the complaints to the ISPs serving those addresses.
OptIn sued SpamCop in May, arguing that its activities interfere with OptIn's business by causing ISPs to block its e-mail marketing.
OptIn also alleged that SpamCop's refusal to disclose the identity of the complainants could add to potential violations of the new US Can-Spam Act, which requires the removal of people from mailing lists if they chose. This, it argued, is impossible unless the complainant can be identified.
The District Court initially granted a temporary restraining order against SpamCop because, according to reports, SpamCop was late in filing its opposition to the suit. The order was rescinded a day later.
Late last month Judge Saundra Brown Armstrong refused to grant a preliminary injunction against SpamCop, on the grounds that the US Communications Decency Act (CDA) does not create liability for service providers who merely publish content created by third parties, and therefore SpamCop is not liable for publishing, or passing on, e-mail complaints from users.
If SpamCop had altered the content of the complaints, said the ruling, there may well have been liability under the CDA.
According to CNET News.com, Keith Valory, lawyer for IronPort, SpamCop's parent company, commented, "We're encouraged that the judge ruled that SpamCop's service is immune from liabilities for publishing or distributing user complaints regarding spam under CDA".
"We think this significantly strengthens the company's position in this case and in the future," he added.
According to a report on Clickz News, a lawyer for OptIn, Steven Richter, responded, "We're disappointed in the court's ruling regarding the denial of the preliminary injunction, but at the same time the judge issued her denial we filed an amended complaint. We believe the complaint has brought to the court's attention more facts for the court to consider as the case moves forward."
