2. Let me make some "IF" if my account was broken of tnc why they not ban me early ?
3. Why I'm allowed to deposit and bettings?
They have banned you when the system found enough evidences to do that. Perhaps, the system was looking for a reason to apply the KYC verification requirement. Blackjack.fun reserves the right to trigger the KYC verification at any time, not related to registration, deposit or withdrawal.
4. Why they asking me KYC ?
5. Why after I did my KYC they said Im created with multiples account ?
Based on the 'PM/Chat Logs', you have multiple accounts on the casino. Nowadays, every casino ask the user to complete the KYC verification if they suspect that the user has more than one account. The casino have your personal details now. They will be able to easily verify multiple accounts of your by applying the KYC policy if you create more accounts in the near future.
I'm neither accusing you, nor taking the side of the casino yet. I just answered your questions. I have sent them an email about it.
