That is why some sites offer rewards to those who can find bugs in the system. Though it was their part to investigate and look for some irregularities inside but as responsible gamblers, we also have to report even though we never get money because there is trust which is most important. As long as the site has not cheated anyone, they should also get respect and no reason to cheat. Cheaters could be found too easily, so we never have to try it because in the end, we are the only ones that suffer the most.
Besides that, there's no point in cheating the casino. After all, the casino will know if we are cheating on the casino because the casino can easily check all of its user accounts. And after being caught, the casino can punish us according to the rules that apply at the casino. If the casino wants, our account, including all our balances, can be blocked easily to make us regret what we have done. It's better to report to the casino if we find a bug so that the casino can immediately check and fix it. After all, the casino could have rewarded us for helping the securities team find the bug.
Trying to cheat a casino cam only be fine when you don't have much money in your account and don't have the plan to stay for a very long time in the casino because it is certain that the person will be ban or account locked as quick as possible. Many of these casinos are always strict and ready to penalize us when we do something contrary to there terms and conditions especially when the person a has some money in there account. It will be unwise for us to try and cheat a casino when we know that the casino can in any ways freeze our account for breaking there team's and conditions.
looking at the current scenario where all casinos or most casinos have placed high requirements for sign-up bonuses, I doubt very much that there are still many cheaters, most people have been playing fair without cheating, I say this because in sports betting there is no how can someone cheat and many casino games also have no way for people to cheat, and the arguments that some casinos have used to confiscate the customers' money that is in the casino account are meaningless arguments and why most of the time the very casino that is accusing the customer of cheating cannot show evidence that the customer cheated
I have seen many cases where the casino accuses the customer of having too many accounts, but when asked: how many accounts that person has, how much money each account has abused, the casino is unable to say and show evidence, and when you go to the casino if you see that to have a bonus there is 30x of the bonus amount and it must be played using deposited money, and when you see the withdrawal requirement, there is a high withdrawal amount and sometimes 3x of the deposited amount, so who the hell would want it having many accounts at a casino with those requirements, nobody. It's hard for people to cheat, and it's a fact that many people have been playing by the rules and some casinos keep inventing things to avoid paying, especially new casinos on the market.
