python spam filter: random words?

[revyakin]

I know fighting spam is like fighting global worming, but still..
50% of spam I get these days contains a random combination of letters
at the end of the subject line. Has anyone tried using that feature in
antispam filters? Since python is the only lang I am more or less
fluent in as an amature scripter, I was wondering if anyone in this
goup has comments on this idea.
Also, is it reivial make a python script filter executable from a
generic mail program like OE, or NS messenger?
I am also wondering why spammers add that stuff to their subject lines
anyway.
