If you're an old player you already knew what you are going to expect in the casino's TOS but you still need to go through it, you don't have to spend the whole day reading and checking but go to the important point that you think will have an impact later on as you play, like the use of VPN and what will contribute to the violation of their rules old players usually know in heart rules that will make their account marked as abusive.
Many gambler as expert or beginner never read above TOS or term of service just start or beginning game if not allow access with normal IP they will try using VPN, later got problem with account is not really worry for some gambler because they only take think can access and play although need help with VPN, but when suspect account have break out rule TOS of casino game they will try to complaint but looks have been late if keep play when casino site have been blacklist on their country and stuck keep using VPN for accessing.
This case will always occur to the people who failed the read the written rules of the casino and later on end up complaining towards the incident happen to them by using certain methods. And when casino found something strange on their account and they been ask for certain verification they deny things and mostly make blame to the casino about what they experience. If they could just read the rules for sure they can avoid those forbidden things which can cause their account to get harm.
