The whole point of the site is to do automated moderation and curation. At the moment, it is so small that it is serving no purpose better than a human dictator would. The whole point is that algorithms can scale. Maybe the algorithms aren't yet ready for prime time and maybe it's better if it grows slowly so that they have time to understand how to modify the algorithms. In particular, I believe that it currently grades users on a single political axis, while with more users it would probably be better to have a more complicated clustering scheme. But you probably won't cause it to grow rapidly, anyhow.
