I’m guessing that would complicate blacklist maintenance quite a bit, which is why we aren’t seeing it work that way.
Most of these blacklists (at least initially) were emergency type measures - ‘block these spammers’, then move on with life.
Blacklist maintainers would need to maintain date first seen/date last seen info, and purge/re-add correctly.
Technically, seems like an ‘append only’ type thing is what they’ve been doing for the most part.
As this evolves and the idea that these do need some kind of expiration or we end up with more maintenance headaches becomes more widely known, maybe eh?
Or if there is some kind of legal rules around it.
