I won 1 BTC in peerbet dice and soon after my account was locked.
After I managed to get a response from site admin in e-mail he accused me of cheating and said I will get my winnings only if i find exploit in the website (?)
After that they ignore my e-mails. there remains 0.8 BTC that i won stolen from me.
I see in this thread and in the website chat that i'm not the only one to have this happen to him.
So I recommend people to stop using peerbet. they will lock your account if you win.
i will edit this post if the issue is resolved.
