Bitcointalk will only rely on the other three unless someone from here comes out and volunteer to be a third-party mediator, he should be independent have not worked in any gambling campaign but has knowledge on tracing fake documents and screenshots, I know the feeling if you are innocent and you are accuse of cheating and there's a big amount involved.
I hope you can do a follow-up on the case of the other two, it's hard to make an opinion if we are still waiting for other reports and you are very eager to prove your innocence.
