Thanks for the pointer. I google-translate-skimmed my way through it.
I don't know about errors with lucky#, but with respect to the voided payouts,
I believe that DadoSovr is victim to a higher degree than being a scammer.
I have seen two dice-games since satoshi-dice, btcdice and btclucky and both of them
were/are vulnerable to starving bets (that is: bets that propagate, but wont ever be confirmed).
Satoshidice is the only one essentially immune to such bets, in that it ties the payouts to the
bets: If then the bet becomes invalid, then so does the payout.
Now I guess, someone seems to have kind of "flooded" btclucky with starving bets,
and got non-starving returns.
Those starving funds were instead paid out to later players. Those, that now complain...
