You're on one for this list.

Regardless, you're likely on various spammers lists if you've done any 
internet correspondence.

The source problem is the ease with which spammers can profit from 
spamming, and all at our expense in having to pay for the extra 
bandwidth and the extra hassle of dumping the stuff. I should know, I 
clean off a few dozen spam mails each day before they hit the maillist. 
Cue Monty Python Sketch: Don't talk to me about SPAM! :-(

CR is one of a few methods to combat spam. All the methods have their 
problems. Shame we can't nuke the /source/ /problem/.

And the MAJORITY of internet mail is spam. Look up the stats for yourself.
