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.
Part of the reason merit distribution is declining is because merit is being received by people who are inactive. Otherwise, merit distribution is declining because people are not spending sMerit as they receive merit.
As merit sources don’t spend their source sMerit, less new merit enters into the ecosystem. If all active merit sources spend all their merit, and the inactive sources don’t spend any, it would appear that source merit is not being spent when looking at the data, but there would be missing context.
