We know that all high reputation users will always get a few points from questions and answers posted long ago. But what I've noticed is that there's a user who hasn't posted anything during the past two years, according to his activity record, and still gets regular increases in his reputation in addition to keeping his all-time rank unchanged. What am I missing here?
EDIT - After reading the explanations given by two users, I don't have any doubts anymore. As I explained in the comments, I thought "passive income" (for lack of a better term) wouldn't be enough to keep one's rank position unchanged for two years. I therefore wondered whether the "powers-that-be" considered that particular user's contribution so valuable as to deserve being honored #1 for life. Now I realize that it's the whole community who has been doing this well-deserved act by upvoting old answers.
