Points to decrease after x days of inactivity

I notice there's a "Reminder for inactive users" in the upcoming version but i'm wondering if there's a feature where the points of users are decreased after the user becomes inactive for xx days. Points keep decreasing as per his inactivity every x days till it becomes 0 points.

This is very important since some users stay on top of the Leader Board after several months of inactivity!!

or is this featured already in existence and i didn't know about it?
