I completely agree that reading reviews and checking the reliability of the casino is crucial, especially if it is a new site that you are not familiar with. As you mentioned, unfortunately there are unscrupulous operators who may try to scam players, so it is important to be vigilant.
I will far leave a casino like that if it continues then there is a high possibility of losing or being cheated by someone under the guise of being an operator, if it is like that then the future will be much worse and there will even be many victims resulting from fraud by operators or people who are not be moral, it is better to play a casino that already has a big name because there are many big casinos on this forum that provide comfort or protect the assets of the players in it because that is much more important than having to cheat the players which will ultimately bankrupt the casino in the future because cases created by the operators who work in it..
A casino cheater will reduce the reputation of the casino, it's affects the house edge and the bettors. It will first affect the bettors who was cheated then the house edge follows, things like this destroys peoples business, so you have to mind the kind of people yiu call to work on your business. Good casino have good review but some bad casinos might also have good reviews as well. Casino that has good names are also reputable, the quality of good casino is different from other casinos that doesn't have singles positive reputation.
