The quality of the subreddit is <i>directly proportional</i> to the moderation. The Ask subreddits (&#x2F;r&#x2F;AskHistory, &#x2F;r&#x2F;AskScience) are consistently cited for having high quality due to actual, transparent enforcement of the rules.<p>That said, moderation works as long as it doesn&#x27;t modify the sentiment of content. Moderation <i>for positive content only</i> leads to groupthink which helps no one. (case in point, Product Hunt, where commenters get upvoted just for saying &quot;cool!&quot; with no additional insight)
