Honestly, I don't see the difference. If you're talking about general low quality posts, look no further than r/PoliticalHumor. And, even though the algorithm has changed, The Donald was ONE pro-trump subreddit and they got banned. They are gone now, mission accomplished.

Now you have about a dozen progressive subreddits hitting the front page on a daily basis with nothing more than screenshots of tweets. How is that any better?
