I don't even think about taking advantage of the bugs in a casino, because when that happens, they will also detect things that are not natural when we win a game for example. When that happens it will affect our account which may later be limited because it is detected and considered cheating. In fact, it is not cheating that we do, but rather take advantage of something that we can benefit from.
Yes you are right, they can announce such things, not for the purpose of contests or the like, but for their interests as well.
Yes, for those of us who only play gambling and don't use gambling as a place to make money, we won't use that bug because it could put our gambling account at risk. If a casino runs a contest to find bugs in the casino, it will attract many people trying to find them, especially if the prizes are huge.
But for some reason, some people still try to find bugs in many casinos to win at gambling. They don't think that their accounts are caught cheating by the casino because they only think of using the bugs to their advantage.
