That seems pretty bad, especially since all of the bets were coming from the same address.
I agree. Looking at some of the transactions, PuraPuraBego created 10 transactions, each spending the change from the previous bet. Nothing wrong with that, and it is a highly unlikely double spend as double spending an input in the middle would make other bets void. I suppose (if they did want to double spend) they might be been waiting to double spend the first input if the net was a negative.
Definitely not double spending, and the only reason it happened was because of your bad system (not accepting multiple outputs as multiple bets, like luckybit does)
If the winnings weren't paid out at all, which the posts in the thread seem to lead, than crazybtrade has scammed someone, regardless if they were RollinCoin or not.
(archive) It appears that no payouts were made to the address
