Most of the online gambling platforms don't share all the information about their team members, so I don't think that a person should only check the team before they decide if the platform is reputable or not. You also don't need to know much about the team behind a gambling casino in order to trust it with your money, it's all about the reputation and reputation is gained by staying in the market for sometime, that's why most casinos that have a good reputation have been around for quite some time already.
For sure, it is difficult to analyze the repute of the casino based on its team members, because no matter how much trusted the team is, still, i don't think it is a wise decision to only look out for the team in order to know about their repute.
The best way to know about the repute of the casino is to get feedback from the players of that casino. There are not many platforms where we may find the honest feedback of the players but we don't need to go anywhere for this information as bitcointalk gambling section is the perfect way to know about the status of the sites, and is it worth playing at any platform or not.
Doing research doesnt really cost you an arm and leg on which it would really be just that normal that you would be needing up some effort and time to do so but doesnt mean that it would be that irrelevant.
