follow the bonus link
wagered a penny, made a deposit and raised the balance from the deposit 6 times the amount that I won from the bonus
in the end, I was simply banned, referring to the rules of the site.
scam casino, do not recommend to anyone.
If you were banned, I am very confident that you broke their rules. You can read in their Terms of Service and check activities that you self-think that you likely broke.
Most common violations that are not tolerated by casinos is cheating with multiple accounts, exploitation of their bonuses for example. I don't say you did it but assume you did it, you should know casinos have lot of data and information to detect suspicious activities especially multiple account cheating.
