They have shoved out the most overtly committed hate and crime subreddits, but they have been promoting only slightly-less savory subreddits to replace them.

The default front page was changed (a few years ago by now) to allow any subreddit to upvote-brigade to the frontpage, leading to flooding by trash subreddits like /r/CringeAnarchy (anti-transgender bullying) and /r/ImGoingToHellForThis (racist jokes) and many flavors of redundant mindless anti-Trump fake-news/clickbait-title subreddits (including /r/esist, /r/politicalhumor, and the ironically named /r/AgainstTrumpSpam which is actually "Against-Trump Spam". )
