That's some typical scamming scheme of gambling sites, sometimes deleting all information before doing it so the users won't be able to have any evidences. I think you should move this to scam accusation even though it's gambling related, I think you should try to inform them too on their ANN thread about the situation and for people to be careful on the site while your issue with the Bitdice is not yet fixed.
Here's the ANN thread of Bitdice:
https://bitcointalk.org/index.php?topic=5304279Do you know how to read? 2 posts above you the Owner of Bitdice already gave His answer and i believe that explains well.
instead of barking here pointing that this site is scammer ? why not post in your own ANN thread here
https://bitcointalk.org/index.php?topic=5267172.msg57985874#newbecause there are tons of issues need to be answered there instead of you circling around other gambling sites.
