What happened:
BitBet stole 10 BTC from me because my bet arrived after the statement had closed. They hide this ridiculous policy in their FAQ and then try to use it as justification for theft. When I brought this to the attention of the community, BitBet and its associates flooded the thread with insults and half truths.

They have run this con game for months now, and many others have been affected. As detailed in their shareholder reports: in March they stole 23 BTC, and in April they stole almost 26 BTC.
