A unidentifiable investment solicitation spammer using an anonymous free GMail address (
email@example.com) just emailed to a purchased or email appended list. The list includes two role accounts originally scraped from a website and Whois. I registered the domain for those accounts in the 1990s, and am the only registered owner that domain has ever had. Neither spammed email address *ever* sent email to anybody; they only received email. The ESP was YourMailingListProvider.
I see that Atro Tossavainen graphed the spam that we saw in January. Atro and I manage a substantial spamtrap collection together, so I have seen what he posted about. Nothing there surprised me except the hugely disproportionate amount of spam Topica sends to our spamtraps. I’ve blogged twice about Topica, and in the last blog recommended blocking their /22 because of the amounts of spam and probability that little or no non-spam email is sent from them any more. However, I did not realize that we were seeing twice as much spam from Topica as from ExactTarget, which sends several orders of magnitude more email than they do.
Florida-based real estate sales firm International Sales Group (ISG) is emailing a list that contains almost a dozen of my spamtraps. Most of those spamtraps were email addresses at real estate firms that went bankrupt between 2008 and 2011. ISG is either emailing a list that they have not contacted in years, or they bought a list or hired an email appender. Their ESP is Vertical Response, whose abuse department appears to have gone AWOL sometime in 2014.
