If they really have given 10 Lamborghini cars in prizes, that is something exceptional but it cannot negate the negativities surround what has become of their website now.
Of course because if you promise that you are going to give 10 lambos, through your respective draws, what you have to do is to give them. Not giving them would be illegal, it would be cheating people.
I find that a bit weird to panic like that if the delay announced of 24 hours hasn't even expired to be honest. If you have made big winnings and you're about to withdraw a large amount it's normal to get a manual review. They seem to have undergone some attacks during last months, especially attacks on customer side so they won't let someone making a large withdrawal withtout reviewing it. You wouldn't be happy if a hacker had been able to quietly withdraw all your balance IMO. Their "review" usually takes several days, less than one week though.
This means that their forms of withdrawal: “Auto” “slow” and “instant” do not make sense because of what has been said and because there have sometimes been delays even in withdrawals of low amounts. They could put a notice saying that due to hacker attack withdrawal processing times may vary, or something like that. But we already know that communication with customers has been practically null for almost a year now.
