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,
