Once the CoC has been decided upon, I have this to say with regard to avoiding further messes and disgruntled community members: The most important characteristics of the CoC and its implementation are transparency and accountability. Whenever a warning/infraction has been given, there should be clear and concise reasoning from the responsible mod - and this reasoning should be made public***. This way if a community member feels they have been unjustly punished, they can cite previous bans/infractions and their context to argue their case - just like lawyers do in U.S. courts. This will force targeted members of the community to build a factual argument rather than relying on the oh so typical "this mod has a vendetta against me QQ". For Christ's sake they might actually have a vendetta against you - now just prove it! If there is overwhelming evidence and support from the community that a mod acted unjustly or irrationally, an appeal should be considered and the mod scolded. At the end of the day we just need the mods to be accountable for their decisions, and then, hopefully, the community members will show more respect and be accountable themselves.
