Active Merit sources can't make up for inactive sources, so the inactive users should be replaced.
For what? So that new merit sources to the same users throw their merit? The current sources have already raised the rates for evaluating posts, it is already rare that anyone throws 1 merit per post, at least 2, 4, or even more. What problems will new merit sources solve? None.
It makes no sense to change inactive sources to active ones so that they just exist.
