there is no way that you will get banned without any violation or reason (at least not from that said site) meaning either you truly committed or the casino is just making cases against you still they are accusing you of something.
anyway try to play only in legit casino like Duelbits.com because it is rarely to find so legit casino that there are so little of issues facing for their years of operation.
Not on Duelbits and other reputable casino but this kind of incident is happening on shady casino which ban their user whenever they win huge amout or consistently winning and already withdrawing their profit. Usually, there’s no problem arise when they are losing or not withdrawing.
They are using their ToS to confiscate the players balance and ban the account without further explanation. This is the reality if you will check the verified scam accusation thread against shady casino which I will not mention here.
They are also making changes to their terms without even notifying the players which makes them somehow violate any terms so casino gets a chance to freeze their funds and block accounts which is why it's advisable to Play over legit casinos only.
