The thing I hate most about reddit are all the little bubbles that are created by bad moderation. Sometimes, this is even automated. You can only post on certain threads if you have the right skin color (r/BlackPeopleTwitter), or ideological disposition (r/conservative) or net worth (r/fatFire).

The absolute worst are when some mod shadow bans you (all posts / comments are silently removed), and refuses to tell you why. I had that happen on my city subreddit, I guess because I said we needed a larger police presence to get property crime under control. That was the only remotely controversial thing I've ever said there.
