Please explain to me the mind of a spammer (Score 1)

It seems like that I did not start to receive spam until I started to post on Slashdot. Then it seems that everyday I receive a choice piece of spam from [e-mail] so I too can receive credit cards or [e-mail] telling me I can quit smoking/lose weight/have infinite sales. I understand transistors and how to solder them to a board, and that's what I do for a living. I do not understand the dynamics of tcp/ip (yet anyway). So my questions are;

The spam I receive is not to any email address I have, but rather to another [e-mail], how can this be so???

Every spam has a different 'remove email address' meaning that I must be on a million spam lists and me getting off them all is not a tractable possiblity. Why can't there be one list that these 'generic' spammers would have to check before doing my inbox?? Perhaps it could be federal law.

Why can't there be a way to 'triangulate' packets to find a physical location for lawbreakers, and give them hard time so other spammers would be scared?? (is scared spammer an oxymoron??)

Doesn't MSN and AOL have ways to keep track of ip addresses they assign dynamically, and thus trace spam??
