I wonder whether there's a membership size threshold where, after crossing that tipping point, the community implicitly looses some degree of transparency whatever the moderation rules are. At some point the increasing impact each decisions have will skew the potential motivations of members and moderators. Intent become very difficult to judge meaning the degree of transparency decreases.

I've seen so many comments from people about the changing nature of some online communities as they grow. Perhaps capping memberships could curb the increasing politicisation of user behaviour and the weight of any individual action would be limited as a result.
