Yes, but it seems really difficult to achieve perfection in any
given list.

This is a proposal for some experiments to see if we can derive a
"carrier grade" list, as Carl Friend called it off list, from
some of the existing data.  Haven't picked any names yet.

Yes, we will not be dumping a bunch of grey entries into any of
the existing lists.

Yes, that's what should happen.  The FPs per existing list should
remain stable or be further improved.  That remains a goal.

I agree.  We should not let that happen.  As far as I'm concerned our
biggest challenge is reducing FPs.  We're already doing a good
job of catching spam.
