Re:filter the subjects (Score 1)

Korean spam subjects must start with [????] or (????) things.
???? is 4bytes korean word which means advertisement.

Of course some illegal spams(is spam legal??) don't have that.

And Korea government passed a law that spams must have @ at the end of subject from 2003 summer.
so, Korean spam's subjects will be like

[????] Hey~ look at this~ You will get million dollars @

or

(????) Hey~ look at this~ You will get million dollars @

South Korea is fighting againt spamers.. but not that effective... -.-;
