Caveat_Imperator just gave a Darwin smite to a 2 month old post made by someone who was a member for 6 hours on Sep 4, 2011 which ended with Commonsense247's one and only post. Then he ran away.
It seems pointless to allow giving karma changes for a post that is too old or a person who has not been active for months.
Is there any way the software can be set up to freeze that?
