I think you meant, they don't create any problems when deposit. Yes, they don't, cause they are well-known scammers. You will get their site super fast, easy to use, and attractive with big bonus. they attract people to come to their site, when you will join, at first they will give you some winnings to withdraw after that when you will come back with a big amount of deposit then they will freeze your account and give you a reason that you violate their TOS. A simple way of scam.
Depositing could not be a problem because nobody knows what you are going to do with your deposit and how you deposited it neither. Of course, it is going to be a problem based on the way you gamble and not how you deposited, how are they going to know what type person you are before the deposit even happens?
This is why I think it is quite honestly obviously that people will be depositing and then do something that will be bad and then it will be hard to withdraw because they are doing something bad.
At the end of the day withdraw is the last place you can catch these people, we have also seen people who failed to even continue gambling, they weren't even withdrawing, they were doing something against the rules and then they got their account frozen and that is the good thing about casinos, they can get to you one way or another but before that you have to do something against the rules and that requires you to first deposit and do it, they can't just ban you before you do anything.
