But for people who don't want to cheat the system, they will report it to the casino that many people do cheating.
That will depend on each people what they want to do with that and if they think cheating is a bad thing, they will not follow others instead will play as usual.
It's like a mission impossible if don't have a benefit to it. I often find the casino just says thanks if someone finds a vulnerable system on their gambling site. Even if it is very important, the casino doesn't give him any reward or maybe a free bet or something. I think the casino management should think about this. Apart to find out the vulnerabilities, the bounty bug program and review site are good for getting many customers also. The casino must open to any report and must give the prize if someone finds the vulnerability system.
That is why those bug bounty hunters are only joining those that have rewards, but if they find a vulnerability, others will really exploit it, and if others find it, they will report it. But that is the problem if those owners don't give some rewards to others. That is why those who find it are mostly exploiting it as they can earn from it rather than being white hats. Though that is really the life of a bug bounty hunter, others will give others a damn about it.
