I see no reason why the listadmins should have to make known who is on moderation and why. People are moderated for good reason. If someone was wrongly moderated (say, punitively), one of the other listadmins would no doubt raise the issue.
Someone who is moderated might not want their name mentioned - they might want to get over their moderation period and get back to constructively participating in this mailing list and in conversations.
