Yes i think the admin in person of lightlord have being following up with events in this thread, and as it is there have not been strong cases of violations or accusations against the casino. This indicates that the admin may have decided to operate in silence.
They surely follow this thread and only check if there are complaints that they have to solve. But if it remains to be a thread of discussions all about the casino, there's no need for them to be active and join unless it's very much needed.
This is part of their platform and to see that some complainants are posting in here, they probably really are checking the thread out for them to solve any problem a customer of theirs dealing with.
