We still don't understand some players, they complaint because all online casinos ask them for KYC to withdraw, we launch a 100% no KYC casino with the only rule of no multiple accounts, and they cry when they get caught with another account
The rules are clear if we found someone with multiple accounts we are going to seize the funds, for this player we found a second account, but he could have a third one since we don't do KYC when we found someone with another account the decision is final.
Sorry but next time read the rules
You don´t make a lot of sense - how does your "No KYC" policy relate in the first place? The dude closed his account a while ago. The account doesn`t exist anymore. Then he decides to come back. Do you have a rule anywhere that people are not allowed to come back after having their accounts closed? Even if you do... read further:
Ultimately, you wouldn`t have cared at all if the player had lost - you know it.
Even if you are within your rights based on your ToS, it doesn´t mean that what you have done is fair and the right thing to do ethically.

I previously tried to argue that to the casino.
Technically speaking, there is no rule being breached as the OP does not have multiple account. He made one, asked for it to be closed, not even asking for self-exclusion [so betcrypto clearly can't counter-argue with gamble aware regulation], and opened a new one much later. There is no malicious intent on OP's overall behavior, nothing is detrimental to the casino, other than the fact that he won fair and square, no harm made.
Their reply for this matter is as follows:
We are sorry but not exceptions.
Also with his second account he deposited around 7,000 EUROS and withdrew 9,000 euros before our system detected that it was a second account.
Once again we are sorry but the multiple account rule is the most important rule for us.
