SendMail CTO Sounds Off On Spam and FTC

CowboyRobot writes "Eric Allman takes his well-deserved turn in commenting on the state of spam, the dark future, and the need for intervention. He calls spam an "arms race" where "in the long run everyone loses (except the arms dealers)." As you might imagine, he's on our side, and he does a good job of clearly describing the current state of spam, and the possible solutions."

      Even if most spam does currently originate in America, if the U.S. somehow passes and enforces an effective anti-spam law, there is effectively zero cost involved in these spammers moving there business out of the States and still spamming Americans.


      As much as I find balkanizing the network to be philosophically repugnant, there is a second step that is not often discussed in the context of US legislation against spam.

      Once spam is banned in the US, we (the network operators) have to block traffic from netblocks assigned to countries that are friendly to spam. The legitimate business and communications needs of those countries will then drive them to enact their own anti-spam policies to get off the block lists. If their only need for the network is to send spam, then they will soon find themselves isolated and ineffective.

    You've asked for statistics, but this is a case where none are really needed. Logic is good enough. What you've asked for can't be all that easily studied. Harvesting email addresses from opt-out lists has to be about the sleaziest thing a spammer could do. And you'll agree that the sleaziest spammers forge headers. So, how on earth could you be 100% certain that your act of opting out has caused a given piece of spam?

    All you can do is look at the spam industry itself, and ask, "why wouldn't they harvest opt-outs for future spamming?" By opting out, after all, you've just given proof that the email address in question is valuable to you. Why wouldn't they want to take advantage of that piece of information. Do you think spammers suddenly adopt scruples on this point? Given how unscrupulous spammers are in every other aspect of what they do, I think it's absurd to think they treat opt-out lists with any integrity.

    That opt-out lists will be abused by spammers is common-sense. I think the burden of proof is on you to show otherwise.

Today, though, I am getting the same stuff, now coming from a cracked cable-modem user.

    If the government would enforce the laws against fraud, deceptive advertising and some of the outwardly criminal schemes advertised via spam by following the money trail, it should put a big dent in the spamming business, perhaps enough that the trailer-court spam king seen on Slashdot lately would have to figure out something else to do.

    I do not believe that a "do not spam" law would work; at worst, the law of unintended consequences guarantees we'll end up having to give John Ashcroft a sperm sample to get a license to run a mail server due to the slippery slope of regulation. At best, we'll have an empty law that punishes no one.

    Instead we've got Ashcroft forming an American Schutzstuffel to protect us from ourselves, and his big anti-crime initiative is to go after people that make bongs. Gee, I feel safer already.

    As long as people willing to commit fraud or other "entrepenuers" feel they can lie, cheat and steal via email with no consequences they will, and someone will be willing to deliver the message for them. Get the seller via the money trail and you stop the spam, and can probably nail the spammer as an accessory as well.

    The spam problem has to do with the whole future of person to person communication, as well as the whole future of adverticement. Whichever way it will be solved, a very likely outcome is that in 10 years it will no longer be possible in any way to get in touch with someone you don't already know from outside the Internet, and the first decade of Internet will be looked back upon with nostalgia as the only decade of totally free communication. This is because the real problem lies in the initial contact.

    You might argue that we can still communicate via boards, chat channels and similar things, where you can give out crypt-keys to those you wish to continue communicating with, but remember that these will be the next target for adverticing after open email collapses. I'm sure adverticers will even write AI's to simulate people so that they can lure the crypt-keys from innocents.

    One of the things mumblestheclown is pointing out is that the fact that you personally are currently managing to filter out your spam is *not* sufficent evidence to prove that the software you are using will be an effective long-term solution.

    The software you're using (however clever it is, however hard it tries to "learn" new types of spam), has easily exploitable flaws. The spammers haven't gotten around to exploiting them because it probably hasn't seemed worth their while--probably not enough people are using the same type of filter yet. But they will, eventually. At which point filters that take a fundamentally new approach will be required. Which the spammers will eventually figure out a way around. Etcetera.

    Most spam filters are designed with the goal of filtering out spam that is similar to currently circulating spam; they make no attempt to resist an intelligent person who has spent some time thinking about how to circumvent the filter.

    Bayesian filters are no exception here.

  16. If everyone would just ... by Skapare · · Score: 3, Insightful

    "If everyone would just ..."

    I hear those words about spam and proposed solutions all the time. But the fact is, and will always remain so, that you cannot get absolutely everyone to do so (whatever that might be).

    Consider the first possibility: "if everyone would just stop sending spam". Most of the spam comes from about 200 or so different spam gangs. Most of the rest comes from a few thousand naive victims that try it once or twice, get cut off, and never do it again (and thus losing their investment into the spamware and "list of millions" they paid some spamgang for). Already, 99.999% of internet users do not send spam. A solution that requires getting so close to a percet 100% just isn't possible.

    Now for the second possibility: "if everyone would just stop reading the spam and buying from spammers". Spam works because the costs to spam senders is so utterly low, that even sending to every internet user is a lower cost than trying to trim the list down to those few people that really want what the spammers are peddling. This goes along with "just press delete". But it doesn't take much in response for the spammers to actually make a profit from their spam runs. And spammer's for hire are making money even if their clients lose money, so as long as there is a supply of naive vendors who are willing to part with their money to get a spam run in their name, spammers profit. Again, this is a case where closing the gap between 99.99% of people who don't even read the spam and the 100% needed to make spammers and their clients go away, is just not going to happen.

    But there is a third possibility: "if everyone would stop using ISPs that permit spam". If even so much as 50% of users who are using ISPs that permit spamming were to cancel and switch to a better ISP that doesn't, that would definitely have a substantial effect on that ISP. I bet even 10% would get noticed, although I think a bit more, like 25%, might be needed to get some of the worst ISPs to act. Of course many people do whine about things like "there is only one ISP here" (not anywhere near 50% face this problem) and "it costs me money to switch" (it costs the victims of spammers even more money for you to continue to support an ISP that is able to give you a discount by accepting pink money from spammers). If we were to simply identify the top 10 worst ISPs for permitting spam to come from or through their network, and get a whopping 25% to 50% of their customers to leave (preferring to go to the top 10 best ISPs for not permitting any spam in or out), this would make a substantial impact and cause some CFOs to panic. And this doesn't require anywhere near 99% to be a successful anti-spam campaign.

    The above campaign can also be pushed harder if many of us refused to accept email from those ISPs (and thus anyone in their network) as a sort of boycott against spam support. Of course there will be whiners here, too saying "You have no right to block my email since I don't send spam" (but if they are supporting a spammer anyway, guess what).

    My whole point is that we need to avoid any "solutions" that make it necessary for absolutely everyone to do something. There will be plenty of people that won't. Instead, the solutions we need are the ones which only require a practical number of people to take that action. If you don't like the ones I propose, then propose your own and say how many people would have to act to make it work.
