How to Kill Spam Without the State

WaxParadigm writes "The Colorado Freedom Report, an online libertarian publication in Colorado, has an article today about How to Kill Spam Without the State. Will our heavy-handed attempts to stop spam through legislation have the outcome we desire?" The article advocates putting the burden on the end user, saying "We must also take personal responsibility to kill spam. We can't pretend the politicians will do it for us. Their incentive is to develop a cute re-election flyer, not solve the problem. If you're still tempted by the political approach, ask yourself one simple question: who is more technologically savvy, your average spammer or your average politician? There are steps each of us can take to kill spam, and to help foster a culture that encourages spam killing." While this forgets the onus of spam on the ISP and telco companies, it should well be part of a multi-tiered plan against spam.

    Spam is revenue for the State, and it isn't a good idea to kill it. Spam has also fetched more revenue for anti-spam s/w firms, than for the purportedly promoted products.

    It stands to reason therefore, that the most likely writers of spam are THE SAME ONES WHO PEDDLE ANTI-SPAM WARE.

    Thus, to kill spam:
    1. Do not trust the State to do anything.
    2. Do not buy, solicit or encourage anti-spam software.
    3. Use free anti-spam tools wherever possible (this is easier with Linux).
    4. Unless spam hogs your bandwidth or disk usage, don't bother.
    5. And lastly, or rather firstly, spend money on a CD Writer and media to take backups, rather than on anti-spam s/w.

    You will lead a cheerful, richer life.

      As I was sitting there deleting stuff, I noticed that on one day she got 203 items. I also saw that she reads spam, and replies to it!

      In addition, those within the ISP who do want to drop the spammers are often not liked. The salesman who brings in a "new" customer at more than the going rate looks good. The admin that kills that spammer's account is getting rid of a "valuable" paying customer.

    We need more than this to stop spam. There's too many idiots about who'll buy spammer's products.

    I don't think SMTP itself is fundamentally broken - we just need some improvements to the administration.

    In the early days of road transport, drivers were unlicensed - anyone with the money could buy a car and drive it. As traffic built up, eventually this was no longer tenable. As email traffic builds up - lack of licensing for MTA operators is becoming untenable. My server has rejected over 1.2 *gigabytes* of malware in the last week (mostly Swen worms). SpamAssassin kills 80 spam messages a day in my mailbox alone - and still about 15 a day get through. The option of "doing nothing" about email is no longer viable. Schemes like "sender pays" are untenable too (and unfair - why should I pay yet another fee to use bandwidth I'm already paying for once?)

    What is really needed is a licensing scheme for people who operate MTAs, just like there is for amateur radio. In brief, here's an outline of what could be implemented. I know this will probably draw the ire of Slashdotters who think they should be able to just run an MTA on their cable modem connection with no qualifications - but this is *exactly* where the problem stems from: to be sure of not dropping too much 'ham' we have to accept SMTP connections from more or less anyone. And this means we get flooded with over a gigabyte of Swen worm traffic in a week.

    This list of requirements is by no means comprehensive - it's just a starting point for discussion.

    * If you want to run an MTA, you must be licensed to do so.
    * A licensed MTA operator may only relay mail from their own network or from other licensed MTA operators. In the case of a home user, this means they can only relay mail from their LAN. In the case of an ISP, from their own netblocks etc.
    * A licensed MTA operator may only receive mail from other licensed MTAs. This means you must reject email from the unlicensed (virus/spam spewing) MTA on adsl-192.14.5.6.pacbell.net.
    * A licensed MTA operator may only send mail to other licensed MTAs.

    MTA licensing can be based on digital certificates. The MTA oper's signature will appear in the header of the email.

    To obtain a license, the MTA operator would have to take an exam. The awarding and administering of licenses will be done by TLD. (A good idea would be that the licensing authority must not be the same company or subsidiary of the company that runs the TLD, so VeriSign is not allowed to be the licensing authority for .com/.net, and Nominet is not allowed to be the licensing authority for .uk, and Domicilium is not allowed to be the licensing authority for .im) There can be more than one licensing authority per TLD.

    The upshot of this is that if a licensed MTA operator passes spam or malware, they can have their license suspended or revoked, or fines levied. MTA operators at the ISP level will be *very* careful to ensure they don't harbour spammers because they'll lose their MTA license. They will be *very* careful they configure their system to not allow executable attachments, or at least scan them for malware. Small MTA operators will be *very* careful not to accidentally configure their mail server to be an open relay.

    To obtain an MTA license, an exam should be passed not for a specific MTA such as Exim or Sendmail, but general good practise in operating an email server, and general knowledge about internetworking - just like amateur radio licenses don't have exams on a specific model of ICOM radio. Additionally, the MTA operator must provide positive ID when applying for the license - this way, we make sure the MTA oper is accountable for what their MTA emits.

    Of course, an actual implemented system like this will be more complex than what's outlined in this posting. Of course, most Slashdotters will hate the idea expressed above - I wouldn't really like to have to take exams to keep running the mail server I already

Require cryptographic authentication of all mail going through any MTA. No exceptions, ever. Every time a mail goes through an MTA, it must be signed by that MTA. Any message without a signature or with an invalid signature gets dropped. By requiring crypto signatures, responsible MTAs can be easily tracked, and spamming MTAs can be blocked.

    Key creation, distribution and endorsement can be through a central authority, though I prefer a PGP-style web of trust because central authorities can abuse their power. Naturally, any MTA caught distributing spam should immediately get their keys revoked, and the revocation should be distributed to MTAs as widely as possible, causing all emails from that MTA to be blocked in a matter of minutes. If an MTA wants its emails to reach its destinations, it will crack down hard on spammers.

    The difficult part is convincing ISPs to require authentication and drop unsigned messages. However, if a large ISP such as AOL or Comcast can be convinced to do this, MTAs will have a strong incentive to start signing messages, and authentication will start to catch on.

    One of the nicest ways is a "teergrube" (tarpit) - a special SMTP server that is tuned to process incoming mail really, really slow, thus making the spammer's tools very ineffective. It doesn't take much bandwith or other resources to run one - everybody who has a computer connected to the net and doesn't need to run a "real" mail server (or is willing to configure a teergrubing proxy that only traps spammers and lets the real MTA take care of ham mail) should do so.

    Most spam is sent via open mail relays. If you are bored or annoyed enough, take the time to read spam mail headers (the interesting one is the last "recieved" line, usually), and inform the admin of the open relay, so that they can close it or get the fuck out of the internet. Also, inform a blacklist like the Open Relay Database, so that mail servers will reject mails from these hosts.

    Try to poison they address databases. Set up a web page invisible for human users that contains lots of addresses that don't exist. But be sure that these addresses also will never exist - only use subdomains that you control, or those mentioned in RFC 2606 (Reserved Top-Level Domain Names), hoping that stupid spamware will try to send to these addresses anyway.

Rather than worry about maintaining lists of email addresses, spammers could feed their message to the network of worms (possibly through IRC, or maybe even an instant messaging protocol), and the network would feed messages to every address listed on an infected user's hard drive, and probably to several variants of the addresses as well.

    www.paulgraham.com

    The idea is to raise the costs of spam to the spammers, if not at the spam sending side, then at the spamwebsite side. Most spam solicits visits to a website. If a relatively small percentage of Net users were to employ Bayesian filters and/or other techniques to identify and segregate spam, then to accept the explicit invitation in each spam to visit one or more URLs provided, and maybe even download the entire sites a few times, the cost of running a spamwebsite server for the tiny numbers of orders they get would rise sharply.

    I don't have it completely automated yet. I'm still using filters in my email client, but they are good enough that no spam gets through to my New Mail folder, and a whitelist ensures that there are no false positives in any mail from anyone I already know I wish to hear from. What goes to my spam folder contains a few false positives of people who have never written to me before, but mostly those whose email contains garbage like HTML.

    Once a day or so I simply save the cleaned spam folder to a file and ftp it to one of my servers. There, scripts take over and faithfully accept the explicit invitations in the spam to visit their websites.

    As more people do this, the traffic will dramatically increase at the spamwebsites, but orders will not increase. At some level or other, either in their server farm or to their upstream provider, those sites pay for bandwidth. As they get bumped up into higher bandwidth pricing tiers, their margins on the small numbers of orders they get from complete nitwits will drop.

    Think of it as a servo system: If the level of spam annoys you, set your filter to fighting back. As more people do that, spam will level off and drop. As it drops to a level at which fewer people bother to set their filters to fighting back, an equilibrium will be achieved. There will still be spam, but a whole lot less than there is now. Think mosquitos and birds. Birds control mosquito populations. There are still mosquitos, but a lot less than there would be if there were no birds. Be a bird -- eat spamwebsites.

    The weak point in Graham's proposal is that it really needs a universal whitelist to prevent spammers or other malicious third parties from causing massive traffic to innocent websites by sending out spam that provides URLs that are not the spammer's. It's not clear how such a whitelist would work, who would run it, how sites would get onto it (or off, if they turn bad), or whether someone will come up with a neat P2P solution.

    It is clear, though, that anyone receiving 20-100 spams a day can easily review the filtered spams or the extracted URLs and simply delete those that appear innocent. Then scripts do the rest.

    The best possible means of controlling spam is to run one's own mail system(s). However, doing so correctly takes decent levels of skill in Unix-type OS's, TCP/IP networking, firewall setup and security basics.

    I don't think it's at all reasonable to expect that all end users of E-mail have those skills. It takes considerable time, effort, and outside help, even for someone with lots of prior network and computing background (it took me about a year and a half), to become what could probably be considered a 'competent' SysAdmin.

    Even assuming the right skills are present, one still needs an ISP that will (1), provide one or more static IP addresses on a broadband connection, and (2), allow their customers to be self-hosted. Such ISPs are, in my experience, rare at best.

    It's well within the realm of possibility for ISP's, the big backbone providers, and domain registrars, to put a very serious dent in spamming right here and now. Some things they could all do include:

    (1) For domain registrars: Be absolutely scrupulous about requiring accurate contact info in ANY domain registration. We're talking valid address, phone number, and contact name and E-mail addresses. VERIFY that information BEFORE issuing a domain registration. Considering that most spammers want to remain anonymous, this simple change alone would throw a huge wrench into spammers' gears.

    (2) For ISP's: Stop hosting spammers NO MATTER HOW MUCH THEY'RE WILLING TO PAY!!! This is a big problem, as spammers are willing to pay serious $$ for ISP's to ignore their own Terms of Service.

    There should be a universal policy of suspending an account at the first hint of a spam complaint regarding it. Once said complaint is investigated, the account should be immediately terminated, AND a substantial clean-up fee charged, if there is clear proof that the account was involved with spamming. If not, simply lift the suspension.

    (3) For the big backbone providers (and they're the ones who could really help if only they weren't as indifferent as the former Bell System): ENFORCE your own Terms of Service! If one of the downstream ISP's they're supplying bandwidth to is infested with spammers, and does not seem interested in controlling the problem, cut that ISP's pipe fercryinoutloud! Tell them that the pipe remains cut until they dump ALL their spammy customers, permanently! If SpewSpewNet (aka UUNet) did this with even ONE of their big spam havens, I think it'd make a huge difference in the Internet's 'Quality of Life' as it were.

    If the ISP in question goes out of business as a result, well, they have no one but themselves to blame for hosting network abusers and criminals.

    Regrettably, I doubt we'll see any of the above taking place. Too much greed vs. too much common sense, and greed usually wins.

  48. True source of spam by pr0ntab · · Score: 2, Insightful

    Is not anti-spam vendors, or people who make money on the few hits garnerned by replies (other than Symantec and Learning Tree, but that's a story for another time)

    Rather, the majority of spam comes from suckers who bought into get-money-quick and be-your-own-boss internet marketing schemes. These poor schmoes in the US and Asia buy these kits, which may even come with rented rackspace out of the US to mailbomb from and proceed to splatter their wares to these double-opt-in lists in the hopes of making a return on their investment.

    Of course, no one is dumb enough to buy any significant amount from one person. They'll keep hammering that list, getting more desperate, trying to "build a customer base" until finally they default on their hosting contract or whatever.

    Meanwhile those marketing "gurus" walk away laughing all the way to the bank.

    They get joe-credit-card-debt-schmoe to do the dirty work for them.

    They don't have to spam or advertise. They just need good placement in google, which isn't too hard to come by these days. The lazy, the "entrepeneurs" will find them, and a fool and his money are soon parted.

    And everybody else has to suffer.

    It's not as simple as just ignore it, or don't buy the stuff.

    Sleazeball marketing gurus will sell you the Brooklyn Bridge and promise you the moon, a 50% response rate if you just use THEIR NEW, IMPROVED SYSTEM

    THAT'S THE PROBLEM!!!

    And if anyone knows how to fix this, they get the Nobel Peace Prize, I swear to fucking god.
