is the trustdice saying that bonus should be used within 30 days and if used after 30 days, its a violation?
they did not say that before the bonus i guess which they also admit that it was set up incorrectly. anyway, its their right to determine whether zemlonq abused it or not. if OP loses all his deposited funds, there wouldn't be an issue. don't you think? assuming he really deposited some btc.
I made a deposit, but I can't show, because I can't enter the account
Any of the administrators of the Trustdice site will see the history of the deposit and the fact that it was from the deposit that money was won
Well, you can show us a transaction from your wallet deposit to Trustdice's address. With a signed message that you indeed own that wallet, of course. The rest can be filled out by checking if the received address in that transaction were from Trustdice or not. Again, even if you had made a deposit or not, the term 'deposit bonuses' is still there. I really want to believe you but it's very hard since both you and Trustdice provide little information. If it is between you, a brand new account and Trustdice with a long-running signature campaign in bitcointalk, you know how bad it's and most people would take sides with the well-known.
That's why when you want to accuse someone with a bigger front and reputation than you, you need to prepare all the information beforehand. Enough to show people you're mistreated or unfair action has been done to you. And pass the baton to Trustdice and force them to come out to address it.
