This is the product of an RBL-style approach (I think FASCS uses XBL).
Indeed they do, and SBL too. The cases I've seen were actually caused
by the latter.
As long as we're only employing tagging-based spam filtering ala
SA/CRM114, this won't happen.
I'm not sure what `tagging-based' is supposed to mean, but the
approach used by SpamAssassin certainly isn't false-positive-proof.
When a mail to my brother was blocked and its sender much confused, he
looked at the spam filter and found it was blocking anything matching
the pattern /cum/. No whitespace around it, and no need for other
`bad' patterns to also match; just /cum/, and it's blocked. He fixed
that pretty fast.
CRM114 is smarter than that, I think. =) So is SpamAssassin.
