It's for both sides the casino and the player. But you can see there are good casinos in there that have been around since, they do have issues but are resolved too. Meanings, these issues can really be resolved if both parties are only willing to exchange and cooperate.
The casinos that don't cooperate, I believe have something to hide and probably have the intention. That's why there is a forum for scam accusations and reputation, disputes are always posted, it is also the same with gamblers who need to post pieces of evidence.
