Good point. I went through and removed several inactive moderators from various boards. Thanks!
It is a good decision to remove moderators who have been inactive for a long time.
And another thing to consider is to appoint new moderators every year through a voting system, excluding inactive moderators. This can improve the performance of users on this forum in many ways. And if those who work very hard for this forum get the responsibility of moderators of this forum, so the forum experience will be even better.
