Several days have passed since the representative of this casino showed up and said they would take a look at the reason why $12000 was confiscated and the player got banned. Since nothing is happening and we still don't know more, I am going to support the player's flag.

I will also give the casino a negative rating as a warning to other players that your money is not safe with them. It's not safe because it can be taken from you and they will tell you "you broke our rules, is there anything else we can help you with today?"

Additionally,
@spyrosc200 You might consider creating a newbie flag against the casino as well. That would be visible to people who browse their ANN thread even if they are not logged in.
Another thing you can do is write a post in Request Support (or Opposition) for Flags here! Make it a good one, with a link to your scam accusation, explaining what happened and how the casino hasn't explained what you did wrong.
