101 Ways To Save The Internet
captain igor writes "Wired news is running an editorial detailing 101 ways to save the Internet from spammers, crackers and smothering regulation. What does do Slashdot readers think of these suggestions, and what other options should be considered to keep the Internet from falling to evil forces?"
The current tactic of ignoring spam "in the hope it will go away" just helps raise the spammers' signal-to-noise ratio when they look at their replies. If they had to go through a million bogus replies to get the 10 that are stupid enough to really want their crap, they'll become unprofitable quickly.
Well, why not crack down on it on multiple fronts. Target the morons buying into spam by advertisements showing how stupid it is and create an effective, international anti-spam effort.
The owls are not what they seem
I was getting a dozen or so spam a day. I started filtering based on the links in the e-mail (which can't be obfuscated or they don't work) and now I find myself checking my mail server just to make sure it's actually working.
Spammers like to use images because that gets them past filters based on words. But images take up a large amount of bandwidth. 25 million messages sent with a 25KB image will take 667GB of transfer. So I simply filter out the domain that's hosting that image.
If you look at spam, spammers use affiliate programs. So although you're getting spam from hundreds or thousands of spammers, there are only a handful of domains they're wanting you to click on or are linking images from.
So you can try to block those thousands of spammers or you can block that handful of domains they're linking to.
And since I'm only filtering links that only spammers use, it's 100% effective and 100% accurate.
Nobody I know is going to be sending me e-mails with a link to www.2004hosting.org but dozens of spammers have and now that I've filtered it, dozens are trying and failing regardless of who they are. So I've effectivly blocked dozens of spammers by filtering a single company.
Lots of spammers also use common click-thru sites to claim their commission. By blocking that handful of domains I've just blocked thousands of spammers.
I now get a spam maybe once every few days and I simply VNC into my server and block the domain used to host the image and I'll never get a spam from any spammer who's using that domain to host their ad pics.
Simple. Effective. I also block mail domains as possible because there is no silver bullet. You have to attack on as many fronts as you can. I've just found blocking companies to be the best out of the bunch. But it's litter and every little measure helps.
