Using Email Networks as P2P Spam Filters

Oscar Boykin writes "New Scientist is running a story on using the social network in email as a P2P network. The idea is that email networks have structure that is conducive to a type of search called percolation search . This means email clients could query the social network of email users to filter spam. This story is based on a preprint available."

  1. Secure? by geomon · · Score: 4, Interesting

    The authors propose that their system have access to inbound and outbound contacts. For trusted email accounts, that might work. But what about email accounts that people may want to creat to sheild their identity (political dissidents, whistleblowers). They would have to live outside of the spam protection network and would, I assume, be seed accounts for spammers.

    Am I missing something in this analysis?

    Since switching to Thunderbird, I get nearly no spam...maybe one or two per day. I like fancy stuff, but when simple works, go with it!

      I use gmail, which does an excellent job at filtering spam.

      But I think this could even be a step back. Like the parent says, I think most informed people have solved the issue of filtering spam pretty effectively (Thunderbird, Yahoo, Gmail, Bayesian filters, etc.) and so we don't generally *see* much spam.

      The *REAL* problem with spam is traffic and network pollution. Spam wastes a ridiculous amount of bandwidth and (through spyware) hijacks our systems' cycles to do something that is (with filters) ultimately to no end. This seemingly won't solve the bandwidth consumption issue and might worsen the problem by polling all your friends over the network and then using your personal cycles to scan said email against all the known spam on your friends' computers.

      People forget that the true detriment of spam these days is the traffic it causes, not cluttering your inbox (if you're smart).

  4. Potential for harm by davidwr · · Score: 4, Insightful

    Imagine the potential for harm if I infiltrated a social network and then identified my enemies as spammers, either deliberately or because I or the software agent I use was somehow tricked into doing so.

    Social network-based spam-detection is a part of, not a total, solution, and its limits need to be recognized.

  5. Isn't this basically how Razor works? by forevermore · · Score: 4, Insightful

    Granted, I just skimmed the article, but isn't this exactly how Razor works? (simplified) Communities of people flag messages, senders, etc. as spam, and the mail server (or in my case, spamassassin) compares the messages to the community spam archive for matches before delivery.

    In Korea, only old people get P2P spam.

    Actually, I think we should find a way to attach the same stigma to spam customers that we do to the spammers. Why do spam customers not have to go to jail? They're as much the problem as the spammers.

    I can see something like having all the spam customers' names published online, so you google for "spam" and "lheal" and up pops my list of purchases. The other spammers then get a very clean list of people to spam. Over time, the net would be segregated into those who like spam and those who don't.

    Yeah, unworkable idea, but so are all the others.

    Your post advocates a

    (X) technical ( ) legislative ( ) market-based ( ) vigilante

    approach to fighting spam. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)

    ( ) Spammers can easily use it to harvest email addresses
    (X) Mailing lists and other legitimate email uses would be affected
    ( ) No one will be able to find the guy or collect the money
    ( ) It is defenseless against brute force attacks
    (X) It will stop spam for two weeks and then we'll be stuck with it
    ( ) Users of email will not put up with it
    ( ) Microsoft will not put up with it
    ( ) The police will not put up with it
    ( ) Requires too much cooperation from spammers
    ( ) Requires immediate total cooperation from everybody at once
    ( ) Many email users cannot afford to lose business or alienate potential employers
    ( ) Spammers don't care about invalid addresses in their lists
    (X) Anyone could anonymously destroy anyone else's career or business

    Specifically, your plan fails to account for

    ( ) Laws expressly prohibiting it
    ( ) Lack of centrally controlling authority for email
    ( ) Open relays in foreign countries
    ( ) Ease of searching tiny alphanumeric address space of all email addresses
    ( ) Asshats
    ( ) Jurisdictional problems
    ( ) Unpopularity of weird new taxes
    ( ) Public reluctance to accept weird new forms of money
    ( ) Huge existing software investment in SMTP
    ( ) Susceptibility of protocols other than SMTP to attack
    ( ) Willingness of users to install OS patches received by email
    ( ) Armies of worm riddled broadband-connected Windows boxes
    (X) Eternal arms race involved in all filtering approaches
    ( ) Extreme profitability of spam
    (X) Joe jobs and/or identity theft
    ( ) Technically illiterate politicians
    ( ) Extreme stupidity on the part of people who do business with spammers
    ( ) Dishonesty on the part of spammers themselves
    (X) Bandwidth costs that are unaffected by client filtering
    ( ) Outlook

    and the following philosophical objections may also apply:

    ( ) Ideas similar to yours are easy to come up with, yet none have ever
    been shown practical
    ( ) Any scheme based on opt-out is unacceptable
    ( ) SMTP headers should not be the subject of legislation
    ( ) Blacklists suck
    ( ) Whitelists suck
    ( ) We should be able to talk about Viagra without being censored
    ( ) Countermeasures should not involve wire fraud or credit card fraud
    ( ) Countermeasures should not involve sabotage of public networks
    ( ) Countermeasures must work if phased in gradually
    ( ) Sending email should be free
    ( ) Why should we have to trust you and your servers?
    ( ) Incompatiblity with open source or open source licenses
    (X) Feel-good measures do nothing to solve the problem
    ( ) Temporary/one-time email addresses are cumbersome
    ( ) I don't want the government reading my email
    ( ) Killing them that way is not slow and painful enough

    Furthermore, this is what I think about you:

    (X) Sorry dude, but I don't think it would work.
    ( ) This is a stupid idea, and you're a stupid person for suggesting it.
    ( ) Nice try, assh0le! I'm going to find out where you live and burn your
    house down!
