After spending some time in some other game discords it's clear that having stricter rules around what constitutes constructive feedback leads to a healthier chat and a better experience for users, particularly new users.
Although unmoderated chat can be seen as a positive, my view, and the idea put forward here, is that acting to address the most egregious offenders will be a significant net positive.
There is precedent in our discord, several accounts were removed from Zero chat for constantly sharing negative views and negative opinions masked as fact. This was widely agreed to be a positive action.
I'm not advocating for strict rules against negative sentiment, such posts are often helpful. But accounts which only post negatives without the intent to drive positive change or which consistently present negative opinions as fact do not belong here.
UPDATE: Note that I made some small edits to the original post to replace banning with addressing (which could mean warnings, timeouts, etc).
