Every casinos has it own requirements and many gamblers do not know this or maybe pay less attention to this aspect, some of this requirements were clearly stated in their TOS, nothing can change it because they put them there on purpose, gamblers always made a complain rue to their non compliance to these regulations and terms, ones you discover you can't cope anymore using a casino, you're free to go and try out others.
What is certain is that gamblers are too lazy to read the TOS in the casino. Hence, they forget what is allowed and what is not allowed so that when they accidentally make a mistake, they think it is permitted by the casino when the mistake is written on it. The casino. Casinos can change the rules easily but must let the users know so they won't be disappointed. And regarding the betting requirements before withdrawing the money, it already exists in the casino, especially if a gambler manages to win an event or promotion.
TOS or terms and conditions in every casino service must be really read by everyone who wants to gamble on a gambling platform or casino, especially if for someone who likes to use large funds in gambling, the possibility of getting a large return must be there, and if Not reading the rules emphasized by the provider, the detrimental thing will definitely approach it, with a quotation sign "literacy" must be increased to keep something unwanted.
Even if there are regulations that are changed, because it seems that there is always a policy update, I strongly agree that the casino must provide notification to each customer either via email or in the casino discussion group so that there is no miss communication between customers and providers.
Yes, it is usually listed, don't forget to always read because every casino has a different policy about withdrawals.
