There are no Onyx Boox moderators:
List of moderators by subforum
Not all forums have dedicated moderators, and the admin-level moderators don't necessarily have the interest or time to run specific subforums (that is why they delegate).
Perhaps, if you have an interest in keeping order in that subforum (and are willing to visit frequently to keep an eye on things), you can ask for moderation privileges there.
Another thing is that there are no prefixes. Per-device thread prefixes could probably help a lot.
