He is not refunding people who are positive in balance. He is refunding people only those that are negative in profit(in loss)
So basically if anyone gambled before 28th and was at 10 BTC profit, and lost to this rigged shit after that will not be refunded(if he is still positive).
SO Even if You lost 9 BTC to this rigged site after 28th. Currently you will be at 1 BTC profit. This means you have left the site with profit.
And Even though you were effected due to the rigged part...you will not be getting your money back and this is wrong.

So people who just had 1 roll effected and are in net negative, will be given back their last deposit completely. And this is more wrong.
They need to work out how much is owed and how much they can payout in refunds then divide it up accordingly. Nobody has a greater right to a refund depending on their past profit's/losses.
