Understandable because what I can see here in this forum is that most casinos do not reveal the proofs publicly for such a case and other cases.
Using mediator like casino.guru is the most used way by casinos or there were few casinos in this forum which sent the proof to reputable member(s) or in other word the reputable member acted like a mediator who can judge the case as a neutral party.
Such info should be behind closed doors, imo.
Because to share is to have approve from all the parties in question, and even Casino-Guru won't make such documents in public view - they will look at them, sure, but it won't be disclosed for everybody.
