Their is a lot of sociology and other research that suggests that ironically these attempts at stricter social/etc codes mostly arise in communities that don't really need them. this happens for various reasons, but it makes intutive sense if you think about it - thoughtful, well-run communities tend to think about stuff like this. but they also, because of that, mostly don’t need it. that doesn’t mean that that it is true in every case, of course.

As someone formally trained in many forms of dispute resolution, I'll also offer many of these have a significantly misguided view of effective dispute resolution. They often think some neutral and objective group of people evaluating a situation is an effective way to resolve code of conduct disputes, in part out of a desire to be fair and objective. But these are social disputes and not contract or other legal disputes. Applying mechanisms meant for one to the other does not make a ton of sense
