Why is there a post limit on Reddit?

• There could be several reasons for your material not being published on Reddit. First and foremost, the Reddit community operates under a set of highly tight rules and a unique score system for posting content.
• Each Reddit user is assigned a 'Karma Score' based on how well their links and posts are appraised by the community. Positive karma will accrue if your posts gain likes and upvotes from your Reddit community. The more upvotes your posts receive, the higher they rank on the Reddit boards, and the more posts you are permitted to share. You must have a particular 'Karma Score' to share your content in a Reddit subreddit.
