Here on HN, we have something absent everywhere else: A moderator who treats you as a person and spends time and energy to explain why something is the way it is. You may not agree with the reasoning all the times but almost everywhere else you don't get the reasoning and only the results(shadow ban, censorship, lock out).
Can I offer you something? If you believe that HN is not run fairly, collect the evidence and write a thorough article about it and post it here or on Reddit and other places. If you articulate your ideas properly and if you have a point I bet you will receive traction and response from YC people.
