Defeating spamfilters through obsession

[The harasser] was hitting me on email and twitter for more than [2100 messages], and the thing was, those all got past the filters I’ve got in place. So one obsessed crazy man with minimal technical skill and nothing but persistence outperforms all the spambots out there, at least on the scale of individuals, if not in breadth of attack.
PZ Meyers

Dr. Meyers goes on to suggest that spammers could defeat filters just by hiring a bunch of people who would manage an ongoing campaign of identical but not quite emails.
Spammers have beat him by at least a decade. In fact, much of the Nigerian 419 spam and associated scams are hand written and sent out by people paid pennies an email to send them.
Where everything falls apart, though, is getting a response. The harasser didn’t need a response from the people he was harassing. So he could go through dozens and dozens of email addresses and twitter accounts a day. Spammers are usually attempting to collect money from people, and they need to have some sort of way for their targets to provide that money.
In fact, a group of researchers looked at credit card processing as a way to stop spam.

95 percent of the credit card transactions for the spam-advertised drugs and herbal remedies they bought were handled by just three financial companies — one based in Azerbaijan, one in Denmark and one in Nevis, in the West Indies.

It was taken as truth back when I was handling abuse@ that if we could stop people from buying from spam, that we could stop the spam problem in its tracks. That failed for multiple reasons. First, it’s impossible to stop people from being manipulated and taken advantage of by scammers. Second, spammers have figured out how to make money in many more ways than getting people to give it to them. Now, a lot of spam is not advertising real products or services. It’s closer to theft or fraud.

End of quarter spam

There has been a plethora of big brand companies doing stupid stuff with marketing recently. I can only figure it’s end of quarter and everyone is looking to pump up their numbers as fast as possible.
I talked about Millenium hotels sending me with an utterly irrelevant ad earlier this week.
@Yahoomail direct message spammed all their twitter followers with an ad for something related to the new Yahoo mail product.
Anyone watching my twitter feed yesterday probably noticed me complaining about spam from Dell.
All of these things are just examples of sloppy marketing. In Dell’s case it’s even worse because they sent me multiple copies of the spam to different addresses. Two copies of the same “SHOP NOW!” email to different addresses, one of which has never been given to Dell.
Mail to the first address is unquestionably spam and I did send in a complaint to Dell’s ESP. That address is never used to sign up for anything. I did try clicking on the “update your subscription” link in the footer and Dell’s website helpfully told me that address was not on their mailing lists. Looks like Dell bought a list.
The second address is one that was involved with the purchase of software from Dell last July. This is the first non-transactional mail sent to that address. I can’t necessarily call the email spam as I did give it to Dell during the course of a transaction. However, Dell could have done a lot better in managing our “relationship” than they did.
Dell collected my email address as part of a transaction in July 2010. They did not start sending marketing mail to this address until May 2011. While Dell is a major brand and most people would recognize the name and may be a little less inclined to hit “this is spam” waiting 10 months between a purchase and regular mailings is a bad idea.  People who don’t use tagged addresses may forget they gave the sender an email address and automatically send in a spam complaint.
Sitting on an address for 10 months means Dell really should have done a welcome series, or even just a single welcome email, to ease the transition from no mail to regular mail. But, no, they just send me an email advertising their sales.
We’ve been Dell customers for quite a while, and all of our purchases have been enterprise grade hardware or software to run on those servers. We’ve never purchased anything remotely like office computers. But the sales flyer was for desktops, printers and monitors. Dell knows what I purchased from there, so why are they sending me ads for things I’ve never bought?
We have our own Dell sales rep, and my only involvement in the transaction is source of payment. Adding me to a product list really feels like spam.
Then there was the email itself.  The “update your subscription” link was broken and told me I wasn’t subscribed to their list. I mentioned it to Steve and he pointed out that particular link had been broken “forever.” How long has it been since anyone inside of Dell has checked that their footer links work?
What is Dell up to? Who knows. But they unarguably are sending mail to addresses that never opted in. And even if you consider an email giving during a purchase process their handling of that particular address was appalling and in violation of almost every good practice out there.

Are you sure? Part 2

There was a bit of discussion about yesterday’s blog post over on my G+ circles. One person was telling me that “did you forget you opted-in?” was a perfectly valid question. He also commented he’s had the same address for 20 years and that he does, sometimes forget he opted in to mail years ago.
As an anti-spammer with the idea that it’s all about consent, I can see his point. Anti-spammers, for years, have chanted the mantra: “it’s about consent, not content.” Which is a short, pithy way to say they don’t care what you send people, as long as the recipients themselves have asked for it.
This is the perfect bumper sticker policy. As with most bumper sticker policies, though, it’s too short to deal with the messy realities.
I’m not knocking consent. Consent is great. Every bulk mailer should only be sending mail to people who have asked or agreed to receive that mail.
But if your focus is on delivery and getting mail to the recipient’s inbox and getting the recipient to react to that mail then you can’t just fall back on consent. You have to send them mail that they expect. You have to send them mail that they like. You have to send them mail they will open, read and interact with.
If your permission based recipients are saying they forgot that they signed up for mail, that is a sign that the sender’s program is futile. These are people who, at one point or another, actually asked to receive mail from a sender, and then the mail they receive is so unremarkable that they totally forget about the sender.
Maybe that’s another reason the question “are you sure you didn’t forget you opted in” from clients bothers me so much. If I signed up and forgot that points to problems in your program, mostly that it’s totally unremarkable and your subscribers can forget.

Marketing or spamming?

A friend of mine sent me a copy of an email she received, asking if I’d ever heard of this particular sender. It seems a B2B lead generation company was sending her an email telling her AOL was blocking their mail and they had stopped delivery. All she needed to do was click a link to reactivate her subscription.
The mail copy and the website spends an awful lot of time talking about how their mail is accidentally blocked by ISPs and businesses.
