However this attitude can cause bug to go unreported, after all an honest gambler may not take advantage of the bug, but if there is no incentive for them they may not report it either, thinking the people responsible behind the website to check for those things will eventually notice it, however if they do not and the first one to notice it this time around is a cheater this could bring heavy losses to the casino, losses which could have been avoided with a bug bounty program.
The casino will look closely at what you are doing when you keep winning, and get caught in the end. Taking advantage of the bugs discovered will not be taken lightly by the casino. As a consequence, they can pretend all things are good and they will make you lose all the time from now on lol that's really a bad ass casino. Yup Karma knows no boundary.
Or the casino will suspend your account with your money frozen. And then they will show the public what you did cause it can't be coincident that you keep doing it over and over with the help of the bug.
The second option is without a doubt the best out of the two, as somehow modifying the results a gambler gets is too close to cheating to my tastes, and even if we could say it was justified in the mind of a lot of gamblers they will begin to wonder if the same may have happened to them already even if they were not cheating, in this case it is better for the casino to simply come clean once the gambler makes a scam accusation and then they can prove their innocence and why they are refusing to pay.
