Well if they feel ignoring the community would do them better then they can continue otherwise they should not expect a community that they have neglected to come their way to patronise their services. Ignoring every important question and points made by the community is very ridiculous and absorb for a casino that is looking for traffic here. Little wonder their official announcement thread is not active as no much engagement here by community members. It is either they take the community serious or the community forgets about them.
First of all, the OP isn't the owner of the site and he has just posted a random review. So even if he isn't online after posting the review that wouldn't hurt the business of the casino that was being reviewed.
Secondly, it could be the fact that OP owns this casino and it might be a shady casino and OP given a good review to the casino, thinking someone will gamble there. We never know what could be good or bad intention of the OP as people come up with different ideas to scam people
