Like I said before, the entire world can know just by going to
http://bitbet.us/faq/.
Bitbet.us's owner:
"The owners of the service decide how it works."
Like has been mentioned before, stating that you are going to steal someone's else fund doesn't make it right.
The service is free to do anything it wants, the user is free to seek legal help for any events that occur.
It is unlikely that anything will happen here in favor to the OP, but it would surely be a step forward to show that fully unregulated business stealing from users are still subject to the laws from the real world even if they are using bitcoins.
