they have reputation over the forum and have large group of players on their casino from the forum so they don't want anything bad happening to them as it will directly affect their profits.They will listen to forum members and managers engagement can put pressure over them to resolve it but the issue must be genuine and you should have proofs for it.
Every type of reputation could be broken the moment a place does something wrong. I mean if duelbits doesn't listen to people here and start to do something that people would not be happy about, then they would end up with nothing at all, I would definitely advice people to avoid making mistakes against a casino, but casinos should also be careful as well.
One "intentional" wrong thing done by casinos would equal to them being gone very very quickly, they would start to lose money so much and suddenly go bankrupt because of everyone taking their money out. Unintentional ones could be recovered and they will drop sharply but could build better, but intentional ones can't.
Yes, you are right, building a reputation can take a long time, but in destroying it that is the fastest thing that can be done without any problem, it is also very taken into account because here what is risked is money and money from clients, so the issue it is much more delicate here in the forum with the reputation, and certainly at any time a person can damage his reputation if he does things wrong. With regard to Duelbits, for me one of the best casinos that exist in the forum, with a very good reputation and also they are always offering a variety of games, this is what makes the excitement in the players increase.
