Have to disagree with you there. The point of KiA2 on Reddit was not to provide a free haven for Stormfags, but to prevent curation by the moderators. If you look at the sidebar on the subreddit, there's even still a rule against posting purely unrelated politics - though I suspended that one because it proved impossible to enforce evenly and fairly, and most users did not want it.

What 'overmoderation' precisely is it that you have a problem with?
