Marcus Evans Conferences: Emailing dead addresses, not giving a damn about opt out

Marcus Evans Conferences are spamming addresses they know to be dead as of Aug 31, 2009 via ESP They’ve been informed on March 17, 2010 and several times afterwards, most recently on Oct 3, 2011. In response to the latest one, Caroline Nielsen of told me just to unsubscribe on Oct 3, 2011. I have no idea how many of these addresses they have in their files, and in accordance with the Data Protection Act, they have a duty to rid their registers of erroneous and outdated data.

  1. As of October 12, more spam from Marcus Evans, this time from their own network.

  2. demand that the spams’ unsubscribes must be clicked (somewhat contrary to Spamhaus advice, Word to the Wise advice, Trend Micro MAPS advice…) and this young fellow responding to abuse @ enta dot net seems to have an unusually hard time acknowledging the fact that domain-wide removal is both the right thing to do AND the sender has a Data Protection Act related obligation to remove erroneous and outdated information.

    As an aside, they’re mailing to an address that can never have existed (think “Käthrin Dzeffösan” for “Catherine Jefferson”). Now since it didn’t exist, how would it possibly have confirmed opt-in?’s AUP clearly requires confirmed opt-in.

  3. It goes on. The most recent message is in perfect Finnish, so the sender, Caroline Nielsen, received a reply in Finnish (only) as well. As did abuse at, the ICO, and the Finnish Data Protection Ombudsman.

  4. Marcus Evans appears to have stopped. But Thought Leader Global is picking up where Marcus Evans left off. How can I tell? Similarity of spam content helps, but hitting the “Käthrin Dzeffösan” misspelled address is a dead giveaway. The ESP is, who have been notified.

  6. Marcus Evans managed to listwash, but they are also spamming addresses that haven’t been live in ten years.
