The casino representative is not very active, it's true. But he visits the forum from time to time, meaning he is not completely absent. Therefore, I would prefer to jump directly to the conclusion that he is completely absent. Since the casino is new to the market, it is natural for the team to be busy completing the rest of the development stages. In general, his use of a Cooper membership account is a good sign of the casino team’s willingness to take their official ANN seriously here on bitcointalk forum.
Copper membership is nowhere near enough to show how serious they are since it's just a starting point basically. They need to answer most queries regularly in order to truly gain gambler attention.
Op of this thread and anyone else from their team haven't been doing that which does not bode well for the future of their site.
