3. That's why a forum like bitcointalk is here. You can get live reviews from the community members on real time basis.
Having a license doesn't mean a business is fair. A simple example is butstarz casino which is registered in Curacao but their reputation is really bad in bitcointalk.
100% true, what is license means to you if the gambling site has a bad reputation in the community, when it comes to gambling and investing, reputation is everything and the only thing that matters, no gambler will play in a gambling site where there are complaints on how they deal with their members.
And gamblers have Bitcointalk to thank for having a category for gambling announcement and discussions it makes things possible and easy to pick the right gambling site to play.
