I understand your concern, but you are asking for answers without a question. That is, you haven't asked an actual question; you have only made statements. I therefore can only presume your question, which makes it difficult for me to pinpoint the response you seek or communicate directly.
I believe your question is: how does the "justice" system protect players from the consequences of their complaints? The only fair and honest answer is: it doesn't. The follow-up is: it isn't calculated to do that. The next follow-up is: that's not its purpose. My admonition therefore is: what protects the players from the backlash is the responses and decisions of staff regarding the complaint.
I have been in a similar situation, which occurred on Victorian Reverie. I never saw the conduct complained of, but only heard, second-hand, that the behavior was driving players away. I directly confronted the accused, who did not deny the behavior, and her reaction to my questioning led me to conclude that she was not a good fit for the game and that the allegations, though second-hand, were true. I removed her from the game, and the players that had been driven away returned.
Apply this to the system: the complainant alleges the accused is stalking other players. Upon learning of this, staff makes inquiries of the accused, whose reaction to the questions leads them to believe that the allegations are true. If the staff is satisfied that action should be taken, then it should be taken. The only evidence necessary is your word and your belief.
Some may cry out: "this is unjust!" Yet I have specifically declined from truly considering the system "just." This is because justice isn't the point of the system; transparency is. While it is admirable to cling to precepts of fair and substantial justice on a game, the fact is that a game is not a nation and staff is not the government. Staff is, at best, like a corporation's board of directors: it has a duty to act in the best interests of the corporation, and can act without regard to "due process."
Staff needs to stop resorting to those notions if it hopes to be effective. Instead, "due process" when dealing with complaints ought to be discarded in practice in deference to "doing what is right." And what is "right" ought not be more than what one's experience and knowledge informs them of.
What transparency demands is an explanation for that action. If your action is justified in your mind, state so. The people may criticize your decision, but no decision will ever escape some scrutiny. And the people should appreciate that you are willing to take responsibility for the choice, rather than hide behind a curtain of confidentiality to "protect" those involved.
