Knowing the rules is an obligation, it's the same as; eating, drinking, and breathing.
Indeed. We don't want to be put in a situation because of our negligence to know their rules right? Thus it's a must for us to do our part before playing to avoid having inconvenience because if you already face a problem on their platform (and you're at fault), it's not an excuse that you don't know the rules.
Anyway, nowadays there are many casinos existing already, that means plenty of choices for gamblers to look for a casino that they prefer. As we know, some gamblers are still not fine to comply if there's a kyc requirement and this is a common issue.
Ignorance of rules or ToS of any gambling platform isn't an excuse in any way so it's a must to know them to avoid breaking or violating them. The casino will not be held responsible if the gamblers or users will be violating their rules no matter how much it inconveniences them.
Yes, various trusted casinos are already available out there and it's our responsibility to know which platform suits us most whether it be on the rules or the overall service they provide to avoid any nuisance later on.
