a per user-bayes don't work for most sites just because you need enough ham
*and* spam to get it working properly and most users don't care enough or
train it wrong (move newsletters they subscribed and to lazy to unsubscribe
in the spamfolder)
a hand trained site-wide bayes works much better and don't demand *every*
user collect enough samples and understand how it works

Being blunt, your userbase can be broadly divided into "clueful" and
"non-clueful". You probably don't have many clueful users whose judgement
and responsibility you trust. Their submissions could potentially be
trained without review.
You can also set up shared misclassified ham and spam folders that
non-clueful users can copy messages to, but those submissions would need
to be reviewed before being moved to the *real* training corpora by you.
Always keep your training corpora.
(This model falls apart at the Large Company and ISP level, of course...)

Justice is justice, whereas "social justice" is code for one set
of rules for the rich, another for the poor; one set for whites,
another set for minorities; one set for straight men, another for
women and gays. In short, it's the opposite of actual justice.
