For me, that's actually a big plus. A rep or admin from the site who is actively answering or posting in their thread. This will give an assurance that if you got any issues from their site, they can possibly help you promptly. Because waiting in vain is annoying. If they will continue to be this active in the thread, I won't be surprised if they will get loyal patrons from this forum.
That's that most important thing after placing some thread here since the exposure what they can get for putting that here will be useless if there's no person will actively handle it and people will just ignore a dead thread since its no fun discussing it with no right interaction with other player also with them.
As for signature campaign yeah its good to have that since this is additional plus in terms of marketing them but I think what most important here is other type of promotion which focus on their casino since this one will attract more gambler to play at them.
