Spam on the Internet is like weeds in a garden. You can avoid both but
only if you don't do much on the Net or in the garden.
A more sensible approach is to assume you will be bombarded with offers
of Viagra, of bouncing Asian teen babes and spy software. Altruistic
souls troubled by your poverty will offer chances to make billions. You
know they really are altruists because otherwise they would make the
money themselves instead of taking the time and care to share the secret
of infinite dollars with you.
Now armed with this assumption, set up a .procmailrc or .forward to block
them. To get you started, my .forward which has a way of scoring mail
to filter spam is attached. I get a certain malign pleasure out of
checking my junlmail inbox from time to time just to have the
satisfaction of having the filter work the way I want.
