Then, after we register and deposit some money, we can win again and when we win, we want to withdraw the money. Still, it turns out that the site tells us that we are cheating. Still, they haven't or don't tell us where the form of cheating is even though we know that we have registered twice on the site and that site has also informed us that they will not allow anyone to register using the same IP or having multiple accounts and they can check every member to find any form of cheating.
How can you say the casino doesn't tell what kind of cheating the person was doing? It could vary from situation to situation.
Also, sometimes the casino can be the cheater, that is when the house doesn't want to pay the gambler and creates an issue to justify an account ban. In this case it's more likely they won't tell the form of cheating the gambler was doing, because there wasn't any cheating in first place.
What do you think? Is it related to morale, ethics or what is your opinion?
It's unethical to not follow casinos' rules like this one, because when people break this rule they show no respect for the platform and its operators who put a lot of effort creating worthful promotions to please customers. And cheaters are actually fools, as on long run the number of promotions will just decrease due to so many trickery attempts.
