I would like to make a suggestion. I suggest that SE considers adopting a policy of Not discussing members publicly on the site. To me it is totally at odds with the sites aim of being Q&A and not a forum, and it brings down any professionalism the site seeks within certain sub sites.
There are ample means concerned members can communicate privately. Through flags, mods opening private chat for a member and email.
I believe by raising the bar on this type of behavior and encouraging members to stay on topic on meta and in public chats, will help to maintain a steady user base on the beta sites. In the smaller sites, community cohesion is vital for the sites to truly blossom and succeed.
I am not saying everyone needs to agree, that would be stale. I am suggesting that back biting of any form be stamped out. With the degradation of social boundaries in many societies, the, relative anonymity provided by the internet, the adoption of such a policy would only assist in circumventing some troubles experienced on the site.
Although the site adopts a policy of transparency, it also has a policy of respectful etiquette between members: What kind of behavior is expected of users? Be nice. I honestly think the site needs to make some clear decisions and give clear direction about it's policies about members discussing other members.
SE may already have a policy in place; if so it is something that needs to be implemented and this begins with the instruction of moderators.
Note: It would defeat the purpose of this post to provide examples. There is sufficient evidence of this on the Stack Exchange sites.
