On the reputation it can be easy to check here in the forum, and the most known scams rapidly get a reputation thread that anyone can check.
True, checking the reputation of certain casinos from this forum is enough for me and this is very helpful. For, commonly this is more honest than taking reviews from certain Casino Site reviews (which are mostly fae and manipulated).
In this case, reputation is influenced by many aspects, including their services, live supports, the trust, how they solve the prpblems, the scam acussation, and alos other aspects.
For me live support and reviews are very important for selecting a casino - since gambling is a money game and there is high risk involved as well.
So make sure - you do your selection wisely and don't get scammed.
