I respectfully suggest
I don't know the structure of the adminstration and moderation of this site. And I've been told that those who are responsible for this structure prefer that the site not be overly moderated. But I think it's time someone took a look at how much space is wasted arguing and/or defending a decision to suspend or ban a member.
I have two suggestions in this regard:
1. Admins and/or mods should be identified on the Home page. Members should be informed as to who to contact if they see something that may be inappropriate.
2. Discussions regarding the suspending or banning of a member should take place among admins and mods and not become a part of the public discourse. IMO, these discussions add nothing to promoting the purposes of N.B. Warnings and final decisions regarding the suspension or banning of a member should take place via pm or e-mail. If these means of communication are somehow not feasible, a brief warning in public from an admin or mod should be sufficient. If there are questions regarding the absence of any member, these could be dealt with in this Forum topic and it should be policy to refer any questions in this regard that might be posted anywhere else on the site to this Forum as well.
