Armoring Spam Against Anti-Spam Filters

moggyf points to a BBC article about how spam can be successfully tweaked to slip past current filtering methods, excerpting "To finding out how to beat the filters Mr Graham-Cumming sent himself the same message 10,000 times but to each one added a fixed number of random words. When a message got through he trained an 'evil' filter that helped to tune the perfect collection of additional words." iluvspam adds "It's an interview with POPFile author John Graham-Cumming that summarizes his talk at the recent MIT Spam Conference. You can still listen to the technical details here (choose the Afternoon 1 session, he starts about 75 minutes in)."

      Hands? Them're luxury! When I were a lad, hands were summat only posh people had. The rest of us had to make do with paws which hadn't evolved fully yet, and we had to filter all of our spam from each mailbox manually, but we had to go to the mailbox - across a river of lava, mind - to collect each message but couldn't filter it until we got back. We'd sort spam twenty six hours a day, getting up two hours before going to bed, and had to eat cold poison while we were doing it. And we had to pay for the priviledge of being allowed to filter our own!

      At a minimum, he would be arrested if he came to the states. However, if someone actually went through with the crime, I'm sure Canada would be willing to extradite him. Canada doesn't want maniacs running around free, anymore than the US does.

      That assumes that beating the shit out of a SPAMmer is a "maniacal" act. I would argue that it is a perfectly rational course of action, and indeed a public service.

      Canada's Finlandization by the US might compell it to hand the guy over anyway, but certainly not for fear of having maniacs run loose (unless you count our troups poised on their border to enforce US Political Correctness Bush Style abroad). :-)

    Spamming is not only irritating, it's pointless. Who is paying these people to spam us? Are people actually buying penis enlarging pills and patches, herbal viagra, mortgage refinancing, credit repair kits, or any of that stuff? Enough to put millions of dollars a month into the hands of career spammers?


    SHH!! If people paying for these things start looking carefully to see if they actually get a return on their investment, all sort of lunacy may follow:
    - Companies may start asking: Let's see, I spend $1 million on making the ad, and another $1 million for a 30-second spot on the superbowl - did I really get $2 million more PROFIT (not sales) that I wouldn't have gotten anyway without it?
    - Producers might realize that there are hundreds and thousands of extremely talented actors willing to work for salaries many orders of magnitude less than big Hollywood stars, are we really getting that many more people walking into a movie BECAUSE it's starring the Governator or Julia Roberts?
    - Sports franchises might wonder why they are paying $40 million in salaries for 5 guys to play basketball to (if you take out the advertising revenue, above) sell 15,000 seats that are probably worth about $15 each in net profit - that's a measly $225,000 per soldout game. 100 games later, they've paid for about half the team.
    - People might start wondering why they are paying $8 to go to a movie, or $100 for an event (concert/sport) ticket, when there are about 10,000 other things better that they could do with their lives.

    That's crazy talk, man.

    Let me take a moment to tell you my sad story. I was in desperate need of penis enlargement, and so I did start ordering those pills. But they proved hard to swallow, and the patches were itchy, and I had an allergic reaction to the herbs in the herbal viagra. Unfortunately, I bought so much of this stuff that I had to refinance my home, and the bank wouldn't approve my loan because of all the penis purchases on my credit cards. So as a desperate last measure, I ordered some credit repair kits, but that didn't work either!

    Fortunately, this story has a happy ending! As I wrote this message, some polite people in West Africa contacted me and I think they are going to get me out of this financial mess.
