Spam Spam Spam Spam Spam Spam...

I am sick and tired of Spam and I know I'm not alone on this. I don't just mean the email kind of spam. Spam comes in many forms. It's far from new, all that's happened is the spammer has new tools.

These are the Spams I hate (in order):

  1. email Spam
  2. Phone calls at dinner
  3. The crap you get inside every statement you receive
  4. Junk mail
  5. The stuff that falls out of magazines

Although 1 and 2 don't kill tress, I find them the most intrusive. I hate the others but not because of the intrusion, I just toss them aside without even looking at them. Which means valuable resources have been wasted. If anyone reading this sends me junk mail. STOP IT. You are wasting your time, money and our planets resources. I will never buy anything from you because of this, so just stop.

At least with the phone calls there is someone to take it out on. You can yell at the poor telemarketer and feel a bit better. Also there are two ways to get ride of the dinner time callers. Call privacy is one, unfortunately this costs money. You can also combat this yourself, by asking to be taken off their list. By law if you ask the telemarketer to remove you from their list they must comply. And it always stops their spiel when I say it.

So what about the worst kind of Spam. The tons of email we get in our email box each day. You can't even reply to these bastards to yell at them. The current thinking in the industry is, creating filters is just not worth it. There is just no way to weed it all out. The best defense would be to make it not worth while doing. If it's not cost effective the spammers will stop. One way to do this is to charge postage on email. If we each had to pay a penny to send an email. It wouldn't cost much and if it meant that the spammer sending millions would stop because it cost to much, I think it would be worth it.

Cynthia Dwork of Microsoft has another idea. Charge for sending email but not with money with Processing power.

What Dwork proposes is to slow down the process by having the sending computer solve a mathematical puzzle created from the details of the message itself. Messages sent at different times and to different recipients would generate a different puzzle. This way a message sent to many different people would have to solve a different puzzle for each one. Thereby slowing down the machine sending emails. She also tosses in a way to combat the fact that processing power doubles every 18 months, by tossing in a variable that ensures each message takes 10 seconds to send. And will increase this value as machines get faster. So for you and I to send a few messages, our machine works away on a problem as it sends each message, so what. For a spammer they would require more hardware and processing power to send out the same volume of emails they send now. Therefore it might not be worth the effort anymore.

I'm behind you on this one Cynthia. If there is anything I can do to help get this through you can count on my support.

    Carl Franklin has neat piece of sw (I forget the name). If you are not on his "approved callers list" and you send him an email - he doesn't get it. Instead, his software sends you an email asking you to verify your identity and a small comment to tell him why he should approve you. He doesn't get the initial email in his inbox, but he does get the "request to approve". Most spammers aren't going to fill this in (I'd wager) as it's a manual process. Once he gets the approval email - and approves you, the sw automatically passes through to him the original email - and subsequent ones. Whew, I made his list.

    Several vendors supply systems that work like Carl Franklin's. You can use such barriers and hiding techniques. But you can also look at it differently. The opposite approach is like the "Take Back the Night" idea...

    Instead of seeking a better way to hide... why not assert your right to use the internet openly. Post your address wherever it could be useful to you and potential contacts... the way the internet should be.

    You will get spam. Use blocklists to filter your mail. Ensure that all spam that DOES get past the blocklist, gets added to the blocklist. Spammers do notice you <grin>.

    www.spamcop.net is a service that works well for me: by using all the blocklists, 70% of spam is filtered out.

    For the few spam left in the INBOX, it takes a few seconds to add their IPs en masse to the blocklist for other users.

    That way you are asserting how the internet should be used... in a way that has an effect (pain and cost to the spammers)... not just finding a personal hiding place.

    Spam is a problem. However I do not want to pay for sending email and my computer is slow enough. I think that vendors must integrate tools to help manage spam. Outlook, because it is common and because it is what I use, needs to incorporate tools to allow you bounce and block email. I have used <a href=”http://www.mailwasher.net/index.php”>Mail Washer</a>, a free tool to help manage POP3 accounts and I have had great success. I have reduced the amount of spam I was getting by 70 to 80% over a two week period in that account. Bouncing email directly from Outlook would be great. Blocking email in Outlook can be improved also. I am using Outlook 2003 and you can add a sender to a blocked list, you can add a domain to your safe sender list, but you can not add a domain to your blocked this. Huh? Did someone forget something here? Refining blocking and adding bouncing functionality within common email clients will go a long way to reducing and managing spam.

    You will never escape SPAM. Take a look at the comments on this post alone. All three of them are flogging some software or server for crying out loud!

    Ever gotten a blocklist even though you are not a spammer? Ever tried to get taken off? Block/black lists are great in theory but fail in practice.

    I recently saw where they arrested some spammers in the US. These guys were pulling down over ONE HUNDRED THOUSAND DOLLARS A MONTH (US!)

    I agree with Mike Tyler that my computer is already slow enough and besides, just how much do you have to slow down the mail processing before you burn up that kind of cash?!? For a hundred grand I can buy a room full of dual XEONS. JUST STOP BUYING THE DAMN STUFF THAT THE SPAMMERS ARE ADVERTISING!

    I have posted before about Junk Mail and how I am inundated with it in so many forms, one of which is
