As you know, sysadmins are responsible for making sure that things run smoothly, that there are no issues with servers, and that different requests from users are completed. Activity is important for sysadmins, whether operations or mw-admins, and inactivity can provoke security concerns.
Therefore, below there is an evaluation of sysadmin activity. All sysadmins are invited to comment and discuss whether any sysadmins should be (temporarily) removed on grounds of inactivity:
In this case, "NO" means that there is no activity for more than a month, so this is a subjective interpretation of "activity"
