What is Crosspost?
A crosspost is Reddit's native content-sharing mechanism that reposts an existing submission from one subreddit into another, preserving the original post's vote count, comment thread link, and attribution to the original author. Crossposting differs from re-posting because the original author is always credited and the content is visually linked — viewers can see both the source subreddit and the crosspost's new community. Not all subreddits allow crossposting; moderators can disable the feature, and some communities explicitly prohibit it in their rules.
Why it matters for Reddit marketing
Crossposting amplifies reach without duplicating effort, but it carries risks for marketers. A crosspost that performs well in multiple subreddits draws attention to the original account posting across communities, which can look like coordinated promotion. Reddit's spam filters also track crosspost velocity — an account that rapidly crossposts the same content to 10 subreddits in an hour is likely to trigger automated review.
How RedditGrow helps
RedditGrow's posting queue enforces safe crosspost timing intervals and tracks which subreddits a piece of content has already been shared to, preventing the rapid multi-community posting patterns that trigger spam detection.
