This is a good read about spam email:

After I read that some time ago, I forward all the spam I get to:
[email protected]
Somedays when the spam is particularly thick, it takes me longer than I'd like to forward all the messages, but it's really gratifying to me to think that these bastards are gonna end up getting theirs in the end (or hopefully, in their rear ends).
