The thing is that no platform would want to deliberately punish a customer if you don't bridge or go against their policy, that why it's good as a customer to read through the policies of a platform so a not to fall victim of these actions taken by casino owners to push people who go against there policy
Some customers try to use these casino platforms to divert funds gotten from fraudulent acts into their betting accounts and withdraw the huge funds without staking on a game, therefore they've come up with different strategies to track users that are commiting such act and that's why they'll always be suspicious of customers that's try to withdrawal huge funds whether you win it from the platform or not you'll have to go through a process to prove your ownership.
However there are still some acts the some casino sites do that i don't find interesting with is changing their TOS without the notice of the customers, I feel if a platform wants to change their policy the first thing they need to do is to inform their customers of the new change of policy so as not to be victims of a policy breach due to ignorance.
That is the fact most of the casino who cares about their reputation tend to follow every rule and regulations and can only punish players on the violation of their terms and conditions and in most cases before there be a substitution to any rule on the terms and conditions of their service, they tend to make proper briefing and creating enough awareness for the players so at to be able to stay away from any possible regulatory punishment that can come along with their decisions of changing the rules if there don't follow the proper guidelines.
But then also, we have some other casinos that may not abide by these laydown rules and may decide to operate as a fraudulent casino that can easily break their terms of service just to scam the players and keep on defending themselves for a long time, so those are the class of casinos we must stay away from to avoid losing all our balance on them.
