r/news used to have a r/The_Donald mod, and as a result, r/news would remove news articles that could make conservatives look bad even if they fit within r/news' posting guidelines.

Around the time of Cesar Sayoc's, the "MAGABomber"[1], mail bomb campaign, even Wikipedia articles like "Terrorism in the United States"[2] were banned in comments, and posts that contained it would have the AutoModerator shadowban the comment instantly.
