Hi MindBender - welcome to the forums.
Spam emails use a lot of techniques to get around spam filters. One is to fill themselves with gibberish to confuse filters & blacklists. Often there will be a sentence somewhere with the actual message it is touting, but sometimes there won't be. I'm not sure why.
Another method gaining popularity is "image spam". As a lot of spam filters become better at picking up suspect words & phrases, the spammers have to find another way to get their message across. So they include a .gif picture which contains the message. There's a topic I posted recently about this:
Image spam increases 200 percent over last 5 months.
All I can recommend is that you use whatever anti-spam facilities your email program has (such as filters & a spam folder). You might also want to have a look at this topic:
What Anti-spam Software Do You Run? for some hints on stopping spam from reaching your inbox.
One thing some spams are doing is fishing for valid email addresses. So you should never reply to a spam as all that will do is confirm your address is "live" and spammers will then sell it to other spammers. It's preferable that you don't even open a spam (or preview it) as many contain code that sends back a message to the spammer when it is viewed. The best thing to do is just delete them without looking at them, or delete them on the server before downloading.
BTW, don't bounce them either (if you have a program with that option). The majority of spams are sent from forged addresses, or by people with infected computers who will have no idea why they are getting bounced emails. Bouncing emails just adds more traffic to the Internet. It's best just to delete them or forward them to a spam reporting service such as Spamcop.
Tracking services so you can send an ICBM wouldn't be of any use due to the above. You would just finish up blowing up some poor family's house whose only crime was to not install a firewall or anti-virus on their kid's computer.
