Well, can you like show it in this forum? Isn't it pretty stupid and obvious that when I asked for you to provide a proof, that also implies that you will put a screenshot or a link to the proof? For now, I won't believe you but the moment that you provide something, maybe we will see what happens next.
They won't provide anything. If there was some sort of proof, they would have shared it in one of their earlier posts.
I am guessing that they got caught doing something shady or lost a lot of money and they are simply venting their frustrations in this thread. Don't waste your time trying to find explain anything to them.
