If pocket dice paid him 100+btc, then there are legit. The negative trust should be removed. Man, it's not easy to pay that kind of amount even u know u can decide not to pay and no one will do shit.
As for the guy that won 100 btc,  I won't be surprised to k ow he cheated.
Why promise people btc and not keep to your promise. They never begged you. U where the one that said you will give. Stupid people everywhere
