Reddit is an inconsistent mess because it's fundamentally reactive at the very top. Someone Who Matters notices they host racist communities? They ban the most obvious ones, but not communities like /r/Sino which are blatantly racist in ways the Western Media finds difficult to complain about. Someone Who Matters notices they have transphobic communities? Ban the most obvious ones, except ones like /r/ShitRedditSays which hide behind a twisted interpretation of feminism, as they could play a more effective card were they to be banned.

And so on and so forth. It's administration by reacting to bad press.
