Casino always do these, these is why my self always trying to read term & condition. People said, no one gonna to read a long page.... I always make it a quick search like keyword "Withdraw" & "KYC".
Why would people says something like that, all i can see/read here is most people suggests to read ToS first before applying or register an account.
But yes, quick search like those keywords helps, sometimes adding "countries" or "country" would help you if possibly your country is part on the restricted lists or not.
There could still be gamblers here who might not have done that practice to read the ToS. Perhaps those are inexperienced gamblers or really doesn't care any and as long as they can register and play and not have issues at all.
Until something went wrong and then they have encountered some problems that they become to understand that it's too late as they didn't read. So it's very important to really read everything, including the fine print and the terms of the casinos.
