• Everything is predicated on 'karma.' Popular posts and comments receive karma, whereas unfavourable ones receive karma and are downvoted. The users with the most karma (particularly comment karma) are the online community's superstars, with enormous influence over the debate.
• Reddit karma calculates a user's score by adding up their upvotes and downvotes. It offers a few practical advantages, such as the ability to create your own subreddit and join some exclusive communities, but it's primarily about reputation.
• A high karma score indicates that a user's posts and comments are well-liked, and so they are seen as more of an authority within the community. A low or negative karma score indicates that the user's actions irritate others, and it usually indicates that the user is a bot, spammer, or troll.
