I believe that the procedure for reviewing cheating cases could borrow some principles from jurisprudence.
For example, presenting an "accusation" in a standardized form (on the forum as a detailed post, rather than in the game) and giving the "accused" the opportunity to provide detailed explanations for all the presented facts in the same format (on the forum) BEFORE a decision is made.
I completely agree with you))) Write a couple of "formal complaints" in the standard format about Rebel, we'll have them approved by an authorized person, and we'll accept them for consideration within the established timeframe of 5 business days. Otherwise, Rebel has been playing without such complaints for 8 years – so it's not a fact that he hasn't started – 1-2 suspicious moves are already a serious reason.
