Mapping the Spam
demaria writes "The folks at cluelessmailers.org have made a map of spam. It shows the relationships among spammers and other entities (legitimate or not), including organizations that track spam, advertises with, shares addresses, emails through, and all sorts of other data. I can't imagine how hard it was to put this together, it looks like a giant circuit design layout, but shows just how big and interwoven the spam problem is."
Well, I'm happy to give up some bandwidth for these guys, it's a cool map. Here's a mirror.

No need to mod me up, I'm not a karma whore.

So I've mirrored it.

It seems to me, that you comment is really extra lame.
'SBEMAIL!' is better than a goat!!
He did no such thing. Shannon's law demonstrates that the information bearing capacity of a communication line is limited by the signal to noise ratio.
It is quite amusing to see how such basic observations are transmorgaphied by the game of Internet chinese whispers.
Spam will be addressed as a problem as soon as the pain barrier becomes high enough. With PKI it is possible to identify an email sender by means of a digital signature. The current problem being that there is no good way to locate public keys bound to email addresses. There is a lot of good work going on in this area, in particular the W3C XKMS group recently discussed a working draft that describes a mechanism for accessing public keys via DNS SRC records.
So under this system what would happen is that when you get email from them the email client would scan your address book to see if they were on your approved sender's list. This would probably include the individuals you know (Cmdr. Taco etc.) and also whole domains (ai.mit.edu) you might trust. if the mail is not in the list it goes into the 'low priority' pile.
There are email clients that do this at the moment but the spammers are using counter measures, such as scanning email list archives and sending out SPAM with fake sender addresses taken from the archive. With PKI and a means of determining whether the person actually has a public key or not this type of filtering becomes much more robust. Incidentally the mechanism does not require S/MIME to work, it can also be used with PGP.
To deploy the solution all we need to do is to persuade email client writers to support XKMS register and locate functions and ISPs to provide XKMS services along with their existing SMTP server. Oh yes and finish the XKMS spec I guess.

I get a bunch of these too.
What's sad about this is that I've figured out the korean characters for "advertisement," by trial and error, and automatically filtered all that junk out of my mail.

Many spammers now seem to put the recipient as the From address. Presumably this helps the mail to avoid certain filters. So in all probability, you're the only one being spammed from your address.
If a spammer's just using your email in the "From" field of an email, there's not much you can do to technically stop them. There are great laws against it (forgery, fraud, misrepresentation, etc.) if you can find out who they are (try to get an IP address, then ask the police for help finding whose it is) but more often than not, you'll get nowhere.
See the linux.org's site for a description of their similar problem (people using *@linux.org as a From address, and people complaining to linux)
If people really do think emails are from you, get into a habit of PGP-signing emails. Let people know that if it's not signed, it's not from you.
Perhaps you might also find a way to autoreply to the people who vent off at you about how evil spammers are. If you get an email with "Re: (your standard spam regexp filter here)", delete it and reply with an explanation. Kmail is good at this, and The Bat on windows (30-day trial) is even better.
So, sign emails. Pity there's not more that you can do.
Or, if you can't read oriental languages, you could do it the easy way and just block any e-mail with oriental characters in them...
I wonder why they even bother having them, but it's a nice way to inform us of everything being done.
For example: eScriptions.net: virtumundo.com: I particularly like the way they go through excruciating trouble to explain "webbugs" though: *pats his Mozilla that displays html mails as plain text and will not load remote images in mail and news (two seperate functions)*
