Re: Interesting article about how spammers beat filters

[Liudvikas Bukys]

A related potential attack on learning filters is
scraping of text that can be associated with the
real interests of recipients.  Scraping could include
both public sources (web), semi-public (discussion lists),
and private sources (documents and emails found by viruses
and worms).  Haven't seen it yet, it'll be a drag when
it happens.
