While reading the article by Paul Graham, something came to my mind;
what will happen if the user is not english?

Let's say 99.99% of all spam is in english (which is my experience), and
my mother tongue is norwegian. ;)
Let's also say that I usually never receive mails written in english.

The Bayesian approach would then put all english words in a bad-words
list (except words found in headers), and all norwegian words in a
good-words list, wouldn't it?
1. What happens the day I join an english mailing list, or receive a
mail written in english?
2. What happens if I receive a mail written in norwegian but containing
a few english words, i.e. quoting someone?

I'd say it would discard mail #1, but let through #2...
What do you think..?
