I'm wondering anyone here has been in contact with MoerkJ (one of D-Addicts admins) since May 16th, 2020 when he was last seen online?

I've tried to contact him to hear if he is okay, but unfortunately without an answer from him, or anyone else.

Knowing that he is mostly interested in Kdramas, it's possible that he might have used MyDramaList at some point.

Is there  something wrong because it's strange for an Admin to disappear

There isn't something technical in particular, but to explain my concern further.

* In 2019 I sent a PM to him, that PM is still sitting unread in my outbox.
* In 2020 the pandemic hit.
* In summer of 2021, there was major floods in Germany.

I don't know exactly where in Germany he is from, but given all of the above, and the fact that he has not been online for a long time makes me very worried.

You should contact the other administrators and moderators to see if they are able to help you
