Um, this isn't exactly a revolutionary idea.  Almost without
exception* the blacklists that are widely used have some sort of
age-out so that the remove addresses that don't continue to show bad
behavior.

The problem is that there's a zillion little networks with their own
private blacklists, where the policy tends to be to add a block when
someone complains, and then forget about it, removing blocks only when
there are counter-complaints.  Talk about not scaling.

R's,
