I stopped using Reddit because I became aware of the strong astroturfing. It is impossible to be a member of any popular open subreddit without being exposed to branding and political ideas. This extends to something like the_D where any whiff opposing ideas are insta banned. It feels like to me these subreddits curate their users to get a specific commentary going. Are they really all collected in their political agenda? I doubt it. They're simply the more vile users who agree to keep perpetuating the hate.

Multiply this to every other subreddit with heavy handed moderation, and it's no doubt that reddit is no longer a fun place to be. There is a constant struggle to control the media that is being presented to the majority unaware redditors.
