Repost

A repost is content—a message, image, link, or video—that has already appeared online and is posted again, either by the same person or by someone else. In general social-media usage, reposting refers to resharing another user's content on one's own feed, ideally with credit to the original creator; every major platform has some version of the action, from retweets to shares. Dictionaries such as Cambridge define a repost as a message, picture, or similar item originally posted by someone else that you put on a website or social media, capturing both the duplication and the act of circulating existing material to a new audience.

On Reddit, "repost" carries a more pointed and often negative connotation. It commonly describes resubmitting content that has already been popular on the site—frequently to a different subreddit or after enough time has passed that users may not recognize it—in order to harvest fresh upvotes and karma. Reddit culture is highly sensitive to this, with eagle-eyed users calling out "repost!" and dedicated communities and bots tracking duplicates. While occasional reposting is tolerated, especially for newcomers who missed earlier viral threads, serial reposting and "karma farming" are widely frowned upon and can run afoul of subreddit rules against low-effort or recycled submissions.
