Recently this question was asked:
This specifically asked about the status of JDługosz who has been a Worldbuilding elected moderator since Feb 2017.
The simple answer is that we don't know where he is. He was an active and effective moderator for some time after he was elected and then activity dropped very low, and then eventually to nothing with no explanation and little communication. We hope he is well and thank him for his contribution during the time he was active, as it is important to remember that moderators are all unpaid positions with people giving up their time to help the community.
His absence and my own need to step back from spending a lot of time is why we held the election of July in this year. The election of two more moderators was to replace him and supplement me. In other words the moderator team is at full strength even with JDługosz absent and myself far less active than I used to be.
In the meantime we are in no rush to act as his presence as an elected moderator presents little to no risk. Even if his account were hacked (for example) all moderator actions are tracked, logged, and reversible. The Community Managers at Stack Exchange are aware of the situation and have made their own attempts to make contact and will take further steps as appropriate.
