What happens when you hit submit and your post enters the mod queue?

When you submit a post, Reddit's system first runs it through several automated checks before it becomes publicly visible. This process is largely invisible to new posters, which can create confusion when a post seems to disappear without explanation. Understanding the pipeline helps you interpret what is happening. Immediately upon submission, AutoModerator — a rule-based bot that moderators configure for each community — evaluates your post against a set of criteria defined by that community's mod team. If your post passes all AutoModerator rules, it is approved and becomes visible in the community's feed. This happens within seconds for most posts. If AutoModerator finds a problem — such as insufficient karma, a banned keyword in the title, a link to a disallowed domain, or missing flair — it removes the post automatically and may send you a message explaining the reason. If your post passes AutoModerator but is flagged for manual review by a moderator, it enters the mod queue, sometimes called the "Needs Review" queue. From your perspective, the post may appear to exist — you can see it when logged into your account — but other users cannot see it. It is in a kind of review limbo. This can happen when your account is relatively new, when your post contains certain content patterns that AutoModerator is configured to flag for human review rather than automatically remove, or when the subreddit uses manual approval for all posts from unverified contributors. Moderators review the queue at their own pace. In large, actively moderated communities, review can happen within minutes. In smaller communities with fewer moderators, it might take hours or days. If your post has not appeared publicly after several hours and you have not received a removal notification, contacting the moderators via modmail is the appropriate next step. Reposting the same content repeatedly while waiting will not help and may trigger spam filters.
