For the three accounts, I have already been told the reasons why the account was banned, although the customer support team and compliance team has told me that
they do not disclose the exact reasons why accounts get banned or locked. However some illegal actions are: Multiple accounts, Illegal Arbitrage betting etc.
Why your team promoting the casino in a public forum if you can't disclose the exact reason of blocking user account? Casino doesn't post the sensitive data of a user publicly. But you have to tell the exact reason for suspecting and blocking someone's account. Otherwise it will raise questions about the transparency of your casino.
