I see you are concerned with other comments here and elsewhere arguing a conspiracy of some sort to get the author banned. I have no opinion one way or the other on that specific accusation. I also don't think it is germane to my claims in this thread.

I was remarking that "Due Process" the specific legal term associated with the how the legal system deals with accusations, was designed to avoid the situation the author writes about where he asserts he was not told who is accusers were, what he was accused of, or given an opportunity to refute those accusations. This works because it removes information asymmetry that can be exploited by the attacker or the attacked. An recent example of how this can be exploited is the story of a venture capitalist who was accused of sexual harassment anonymously by someone who turned out to be a competitor[1].

In a system where, as part of the process, an accuser and accused are made aware of the real identities of each other this would never has passed the first examination.

If such a process were in place in this particular case, and the code of conduct violation was the one you cited, then the email to the author would have said

   "These {insert identities} have accused you of failing 
    to enforce the code of conduct elements {identified paragraphs}
    in the following situations {links to exchanges between author
    and community}. We would like to hear your side of this 
    before we render a judgement." 

Processes are like programs or math proofs, if you do each of the steps in the right order you get the right answer regardless of the intent or opinion of the people carrying out the process.
