What is reddit automoderator?
Last updated: June 2026
AutoModerator is Reddit's built-in, rule-based moderation bot. Moderators configure it to remove, filter, or flag posts and comments automatically based on keywords, links, account age, karma, and other conditions.
Key takeaways
- AutoModerator runs on rules each subreddit's moderators write, so the same comment can pass in one community and vanish in another.
- Common triggers are new or low-karma accounts, certain link domains, banned keywords, and posts missing a required flair or format.
- Removals are often silent; checking your comment from a logged-out window is the fastest way to see if it was filtered.
AutoModerator, often shortened to AutoMod, is available in every subreddit. Moderators give it a configuration of rules, and it checks each new post and comment against them within seconds. A rule can remove the content, hold it for human review, add a flair, reply with a message, or report it to the moderators.
Most rules target spam. Typical examples: remove comments from accounts younger than a set number of days, filter any post containing certain link domains, hold comments that include words like “discount” or “DM me,” or require a minimum combined karma. Moderators rarely publish the exact thresholds, because publishing them makes the filter easy to bypass.
For lead generation, AutoMod explains most “my reply disappeared” moments. Your comment was not rejected by a person - it never reached one. The fix is usually an account with real history in the community, replies without links, and following the posting format the subreddit asks for.
Examples of reddit automoderator
- A two-day-old account replies to a buyer with a helpful answer; AutoMod removes it because the subreddit requires accounts to be seven days old.
- A comment containing a shortened link is filtered into the mod queue and approved hours later, after the asker has already chosen a tool.
- A subreddit's AutoMod replies to every “what tool should I use?” post with a pointer to the weekly recommendations thread.
How to keep your replies past AutoModerator
- 1Read the subreddit's rules and pinned posts - most AutoMod rules mirror the written ones.
- 2Build some history in the community first, since account age and karma are the most common thresholds.
- 3Post without links unless the subreddit allows them, then check from a logged-out window that the reply is visible.
Why it matters for lead generation
Timing matters on buyer-intent threads: the first useful answers get read. A reply held by AutoMod for hours, or removed entirely, loses the buyer to whoever answered visibly. Knowing the filters keeps your answer in the thread while it counts.
