Let me add that I think it is in order to make an even more detailed distinction to render justice to the matter.
The four toungs / for ears model I linked above conveys, copying the gist from wikipedia:
- The Factual Level contains statements which are matter of fact like data and facts, which are part of the news.
- In the self-revealing or self-disclosure the speaker - conscious or not intended - tells something about himself, his motives, values, emotions etc.
- In the Relationship-layer is expressed resp. received[ clarification needed ], how the sender gets along with the receiver and what they think of them.
- The Appeal contains the desire, advice, instruction and effects that the speaker is seeking.
I’d argue, within the boundaries of this model, harrassmemt may probably only (or at least overwhelmingly) take place within the relationship category, since all other category are inherent non violent comunication.
Remains the issue, if it is possible to separate those other categories and if we want to provide some.sort.of guarantees for remaining those channels open (through an intermediate, as you suggest, or whatever).
It seems to be uncontroversial, that in the context of most incident of possible harrassmemt, there is also legit needs of communication involved.
At the very least, the four ears model should be part of the standard tooling for moderators. i hope I was able to show that by this post.
