I know Baby, it's improved, but it's far from clean... and it's the same in some other casino char rooms! Well, I would be very strict about this matter! I believe the same people are doing this in different casinos...
That's quite true. Most users are spamming on the chat and once you send messages like you won or something then random girls start adding you as friend with the sole intention of asking for some coins.

Most probably they are fake ids I believe.
I think bc.game can implement some kind of wait time on the chat so that once a person sends a message he would have to wait for sometime to send the next message.
Especially if there is a big winning, everybody tends to be even more active and asks for money. Waiting time before sending a message or maybe increase the requirements before you can chat in combination with a lot more moderators should help in reduce in the chat. Even if they do all this, you will not see me on the chat lol.
