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=5304279Really you have the face to post here about scam site activities when you can clearly use your Signature as an example of How scammers gambling site goes?
I remember Bitdice runs one of the long running signature campaign in this forum though there are some issues thrown towards them ? @BoXXoB continues answering every single details so i think that calling Bitdice as scam literally is not on your Jurisdiction , show strong proof and you will have your rights .
