I agree with you because any platform neither exchange or gambling platform that sell out their customer information to scammers that is a process of bringing down the particular platform so I know quite well that many people do owns a platform does not like to review it to external people so that they are platform will you continue to have a traffic so I believe that that is one of the reasons no team of a casino gambling platform that will be able to review their secret to any scammer because it you really in danger their platform so I believe that if then try that it will cost a lot of damage to them reputation will not be valued
The team of the casino may not be involved in such activity but there are some greedy staff in the company that can do that. We can give benefit of doubts to some reputable platform but you don't know so well what is going on behind the scene.
I don't think this could be easily done because all the info will be with the casino not individual self. In case this kind of thing is happening, I think it could be from the team or the customer cares to make things difficult for users so that they would be complaining and having issues and complaining everytime. This is not ordinary and I see no reason for this. Many of these casinos can be deceptive looking for quick users to use their platform so that they can start making money from themselves. The competition in the gambling world is what do make some casinos to always lie so that they can keep having flow of traffic from new users.
