Naturally the "this is rigged" etc arguments will start rolling in but at the end of the day anyone can mathematically verify all rolls they made. I'll explain how he managed to get an unhashed seed when we've resolved this. Working on it now
Quite a big theft then but then he probably ran into the hot wallet limits? Also, he was doing it again as user pahahaha but you're probably already aware of that. Looking forward to the statement about this.
