Do you think regular users would know, or even care about which category to use? As far as they're concerned, it's "this message bad!", period.

That's why Gmail is fantastically bad at spam filtering. Even simple spamassassin setup is miles ahead of it. Gmail filtering is basically useless because it forces me to check spam folder and I need to look at all this spam anyway.
