The simulation of a "community" falls short on several social aspects typical of a community, mostly through technical reasons of interaction only via the software.

I think a very useful feature would be an area which showed statistics across the userbase, particularly a ranking of the most ignored users to help newcomers identify trolls which are not otherwise moderated.

In any other community, you can tell who is ostracized as anti-social, but not in this environment. It is a behavioral observation loop that allows both the individual and community to be objective about social behavior and modify it if desired.
