Who are you talking about, you can't just come randomly on the casino ANN thread and start saying trash without any exact point. You did not mention Yes bet in your comment and yet you posted this on their thread, well if you must know, Yes bet has been around for a while and to some level, there has maintained its consistency and also improve on some of the features, am sure if the casino has any questionable character their wound have been exposed by now.
But to the extent I know is that their customers have not complained of any withdrawal issues.
