Selling Your Attention to Spammers

Dotnaught writes "Can the free market stop spam where technology has failed? As described in InformationWeek, Professor Marshall Van Alstyne of Boston University School of Management has co-authored a soon-to-be-published paper that proposes an "attention bond" -- money put up by email senders that recipients collect only if they consider the message a waste of time. Supposedly, this market-based filter performs better than a perfect technology-based solution, with no false positives or negatives. A company called Vanquish already has a working model. Is selling one's attention the answer to spam?"

      A "Sorry dude, but I don't think you were reading" is definitely in order.


      From the article:

      Imposing a cost on spammers isn't exactly unheard of. Return Path Inc. uses financial bonds to improve message delivery and deter spamming. The difference is where the money goes. If a participant in Return Path's Bonded Sender program sends spam and generates enough complaints, the sender's bond gets paid to the Internet Education Foundation, a non-profit Internet advocacy group. And since participation in the program is voluntary, spammers can simply forego the greater rate of deliverability they'd get in the program and rely on volume to overwhelm filters.

      The idea of making senders pay conditionally upon the recipient's attitude toward the message is so old and tired that the "market-based" aspect of this solution might as well be absent from the article. The interesting question would be how, technically, to set up such a system.

      From near the end of the article:
      Despite the obstacles, Van Alstyne has faith in the curative power of the market. "If you can assign property rights in the problem, then you get efficient trading on it, then you get a better solution than almost any other possible alternative," he says. "That's why I think it will work."

      Wow, dude, sorry you got hit some moron posting crap at you. I get nervous every time an AC replies to me.

      To answer your question, the reason spammers can't hide from this is that they have to pay money to send messages via this mechanism.

      In the limit case, you can choose to receive messages ONLY from people who send mail this way. Even your friends would pay money to send you email, but since you'd mark all of their messages as "worthwhile" it wouldn't cost them anything.

      You'd get no spam, but you'd lose the ability to get mail from anonymous sources. Sometimes you want that (e.g. potential customers sending you questions.) It would also make it hard to subscribe to things like joke-of-the-day services, since they'd have to filter out dimwits who subscribe and then mark the message as worthless to receive the attention bond.

      If you don't go all the way, you can still set messages coming from this service to bypass your spam filter. Existing spammers can continue to spam, but they risk being filtered out. It would help you tune your spam filter better.

      This is aimed at people genuinely marketing genuine products via mass-email. They're basically paying you to read their ad, which means that they're going to be a bit more selective about whom they send it to. This is spam sent by people who don't wish to hide, to people who wish to read it.

      Say you're a grocery store and you want to send out coupons every week. You send your message out via this server, and pay $.01 per person to guarantee that the message is worthwhile. Then you have some mechanism so that you only send it to real opt-ins, who somehow guarantee that they won't take the money. The message goes out, people get their coupons, and you get all of your "attention bond" back.

      The "some mechanism" for guaranteeing only opt-ins is the tricky part; it's prone to people scamming it for the cash. So there are variations of this plan, but basically they all crumble under the weight of lots of small bits of money moving around, which is currently too expensive to solve.

      So I hope that explains the thing you think you're missing: spammers can't hide because they don't want to hide. They want you to read it and are willing to pay in advance. They're then free to spew all they want, but it'll cost them big time. Spam only works when it's basically free, since the response rate is so low.

      It fails, but not because the spammers hide.

Child pornography department just fills in the vacant slot or two and the experts train the newbies. Thats how it should be done .. let the domain knowledge permeate the entire law enforcement departments that deal with online crime. You're not dismantling the original group, you're just letting them share some of their expertise with other departments that so clearly need them .. expertise they had no choice in gaining from working in such an important field.

      There doesn't seem to be much motivation to put that kind of knowledge on spam enforcement, but I think the parent poster is right: why isn't there? Obviously spam isn't nearly as bad as child pornography, but judging by some of the porn sites they advertise via unsolicited spam, the industries certainly intertwine. Its not like a potential victim becomes a stupid slut who made her own decision to sell her body the second she goes from non-legal to legal age. I've seen enough stuff in my lifetime to know that claiming you're a consentual adult isn't exactly 100% true if somebody is pulling your strings.

    Attention bonds don't work, as described here in more detail:

    * Creates money trail alongside email trail, making legitimate anonymity almost impossible

    * Makes trolling a profitable business model

    * Participants who are poor, or not allowed to form legally binding contracts (such as children) can't have email anymore

    * If only applied to email, moves the spam problem to other media without solving it

    * Creates obligation for email receivers to actually pay attention to the messages of paying spammers; can't set the price high enough to make that okay, without chilling too much non-spam communication from senders who can't risk being forced to pay a large bond

    * Can be used as a payment system for underground economy (porn, gambling, drugs, general money laundering)

    * Mustn't allow any communication beyond the bond amount, or else that'll be used for spam; but the bond amount isn't really enough information to make the read/don't read decision

    * Senders often don't have the choice of talking to a different receiver on a given subject instead, so system can be abused by anyone you NEED to send mail to (e.g. legal notices, tech support, recipients of emergency communications, etc.)

    * Human beings known to behave irrationally when involving transactions in small amounts of money (same reason micropayments fail)

    * Creates complicated international payment system with huge numbers of participants; not possible to keep such a system secure. (Like credit cards but a thousand times worse)

    * Large companies like Microsoft will use embrace-and-extend to create/extend monopolies and punish users of competing software

    * Probably already subject to conflicting patent claims

    * Creates need for middleman businesses that have no other function; opportunity for abuse, like the domain name registration racket.

    * Escrow system likely to end up using anti-robot captchas (like domain name registration), making legitimate non-human, and disabled human, email users unable to participate.

  31. The Only Solution by _Hellfire_ · · Score: 2, Interesting

    The only solution to spam? Replace SMTP.

    SMTP is an outdated, insecure protocol which is ill-suited to modern email.

    We need to replace it with a protocol which is authenticated at both ends. A friend and I came up with the following; which although not perfect and probably subject to a few tweaks is a step in the right direction.

    J Random Hacker/Company/Joe Sixpack leases a domain name from J Random Registrar. Let's call it jrh.com

    That registrar provides a private key and a public key pair based on the domain name.

    The CMTP (or Complex Mail Transport Protocol - I made that up) server on jrh.com wants to send an email to target.com. It signs the outgoing message with the private key (ie puts a hash in the header - and you could base it on time and date or other arbitrary data to make sure there's no forgery) and then connects to target.com. target.com then asks jrh.com's registrar for jrh.com's public key (either that or it's propagated over DNS). If the pair match up, the email is accepted. If not it's dropped at the door. No questions asked.

    During the phase in period, SMTP traffic could be configured for a 15 minute delay on each target server, whereas CMTP traffic is dealt with immediately. I compare it to how Telnet was slowly phased out in favour of its more secure replacement, SSH.

    So, if a spam zombie Windows box is spewing out SMTP traffic in a CMTP world, most servers would drop it at the door. The spammers can't go to CMTP because:

    1) They can't use a private key they made up because it's checked against the public key held at the registrar.

    2) If they use the private key of a domain they hold (ie install it as part of the worm infection) when people get even 1 spam from them (yes 1 spam - it would be that unusual) the server just ignores mail sent with that signature.

    The solution works because the motivation would be there for companies to prevent spam on their networks. As soon as they switch to CMTP, they get no spam over it. And eventually they will get no SMTP email at all. Just as nobody uses Telnet anymore, SMTP will die out if replaced with something better. You can make all the laws you like but at the end of the day, the SPAM solution is a technical one.

    You've either failed to read the article, or misunderstood it, though you were closer than the first checklist.

    () Lack of centrally controlling authority for email
    -- it doesn't appear to use this - it appears to be recipient's-end charging, which can be deployed in a decentralized manner
    () Open relays in foreign countries
    -- those don't matter here - if they sender doesn't pay, the recipient doesn't read it, and relays only make it harder to pay.
    (*) Mailing lists and other legitimate email uses would be affected
    -- you correctly marked "whitelists suck", which is part of why it's hard to implement this one correctly.
    (*) Users of email will not put up with it
    -- this is the big problem with TMDA, hashcash, and many similar systems
    (*) Many email users cannot afford to lose business or alienate potential employers
    -- you missed this one too. See previous.
    () Requires too much cooperation from spammers
    -- not a problem. This one requires cooperation from non-spammers.
    () Unpopularity of weird new taxes
    -- unless I grossly misread the article, this doesn't apply here - the sender pays the recipient or recipient's ISP, not some third party.
    (*) Public reluctance to accept weird new forms of money
    -- Yup. Either you need weird new money or old-fashioned real money, and the latter is usually too expensive per transaction.
    (??) Armies of worm riddled broadband-connected Windows boxes
    -- Maybe. If enough people start using this, and there's a convenient mail-sender interface so senders don't need to pay attention very often, then worms will start to abuse it. Otherwise they won't care, and the five people who still use it will have whitelisted each other.
    () Dishonesty on the part of spammers themselves
    -- Doesn't hurt the recipient, who sets the price high enough that he's willing to read an occasional Nigerian Herbal Fake Vi***a ad and keep their $5 just to annoy them. This proposal suffers from dishonest recipients, who convince legitimate that they should be willing to pay the money to get the recipient's attention. It's a serious enough problem that it can even lead to "Make Money Fast By Reading Email At Home" spammers inviting you to become a recipient :-)
    () Why should we have to trust you and your servers?

If I'm a sufficiently interesting public figure, like Rush Limbaugh or Daily Kos or the Editor of the New York Times or Britney Spears, maybe you'll pay to get my attention.
