Or they will lose a decent amount, and then they will already understand that the game was dishonest) I would gladly tell the casino so that they can protect themselves for a reward.
Not many people would be happy to tell a casino about a bug in their casino but instead use it for themselves. If you have such intentions, you have good intentions and it will give you something and the casino will probably reward you. It will be better for you because you are not using the leak in the server personally but can tell the casino so they can fix it quickly.
You're right. Not everyone will be a good guy in telling a casino or gambling website that their sefurity has been infiltrated or has a glitch. This is because most of the time, people have the tendency to be selfish and greedy. Sometimes people really don't say a thing so that tjey can utilize something.
If you have morals and principles that you uphold, definitely you will not be okay with this because this is still a form of cheating. However, not everyone could be like that and that is the sad reality. Perhaps what the casinos could do is have a team that will check their system and security every once in a while so they won't experience such abuse.
Sometimes the need for money is much bigger than any moral you might actually have.For example if that guy who has found a glitch which can make him like 1 million dollars which happens to also have a big family and this amount can secure his lifetime future I find it very difficult for this person to abide by the morals which I believe he should do but the pressure to change life and make it secure financially at least for 1 generation is much bigger and tempting.Human nature is well known to fall prey of greed in a lot of circumstances so I believe in the end it would be based on the type of glitch you found,the more money it makes the less prone to tell about this,unfortunately this is human nature.
It takes a lot of learning and discipline to abide by morals,a lot of time which can be destroyed in just a few seconds by greed like in the above example.
