Uh, what if not? Yeah, it can be true, but having a respond from bc.game that there's nothing they can do where they have everything the reason to tell the user what term was violated. Well, as long as OP never posted the chat logs then people will just speculate.
That's it, no one can tell. If you're on the casino's feet you'll do that kind of assessment, but likely on their side they just want to prevent cheating on their own platform. I don't think the chat logs would make any difference if the damage has already been done.
In such cases, its the user that is at fault since bc.game is a reputed site and won't do such acts without any valid reason.
Besides that since OP hasn't provided much info after he posted this thread it gives an edge to the casino.
May be OP cant back up his claims hence became inactive.
