Reddit Deploys AI Moderation System Rules Hub to Replace Automod Across 100K+ Communities

Reddit is introducing a new moderator: AI

Reddit is enlisting AI to help moderate new subreddits -- and eventually the rest of site. The company is introducing automated moderation tools that rely on LLMs to help mods manage their communities, and it's expanding who can use those tools today ahead of a full launch later this year. The company calls the suite of tools "Rules Hub," and the tools let mods decide what rules should be automatically enforced and what should happen when a rule is triggered. Rules Hub relies on LLMs to evaluate "whether a post or comment matches the intent of a rule," which "allows Rules Hub to better handle nuance, natural language, and edge cases while preserving moderator control," Reddit says in a blog post. Right now, many subreddits use tools from a feature called Automoderator (aka Automod) to take action on rules, but Automod's tools "depend on exact keyword and pattern matching." Reddit says that Rules Hub has been in testing for "the past few months" with "new and experienced moderators from over 700 communities, including members of Reddit's Mod Council Network." That test of Rules Hub is now expanding to "all newly created communities" and will be "widely available" at some point later in 2026. Rules Hub will be optional for new communities, spokesperson Rosa Kim tells The Verge. However, it does sound as if Reddit plans to retire Automod's enforcement features down the line: In its post, Reddit says that "Looking ahead, we believe Rules Hub, together with newer systems like Post & Comment Guidance and Safety Filters, can eventually replace many of the enforcement workflows that communities rely on from Automod," Reddit says in its post. The updated mod tools are just one of a few big platform announcements Reddit is making on Wednesday. The company is also planning big changes that will affect developers: It's going to require new third-party apps to use the developer platform instead of the API. "We envision a future where all good, trusted automation on Reddit runs within an ecosystem that allows us to offer support and enforce our policies consistently," Reddit says. "To achieve this, we will continue supporting limited public API access, but we will gradually restrict new requests and require third-party apps to transition to and operate on Reddit's Developer Platform." The shift follows Reddit's major API changes in 2023 that it put in place to get AI companies to pony up for Reddit's data but also caused widespread backlash in part because they forced many beloved Reddit apps to shut down. (Currently, if a developer wants to make a Reddit mobile app, they have to get permission from Reddit to get public API exemptions, and that will continue to be the case, Kim says.) Reddit doesn't have a "set timeline" yet for requiring the developer platform, but the company will give "give the community ample notice" and provide a clear timeline, Kim says. The upcoming change will affect "all API apps except the ones we explicitly grant exceptions to," according to Kim. Reddit is also saying today that it's planning more changes to old Reddit as part of its ongoing efforts to fight unauthorized scraping of its content. Those efforts already include blocking Reddit results from search engines that don't pay, suing Anthropic and Perplexity, and blocking the Internet Archive to stop AI companies from using it to scrape data, and in June, the company announced that people would have to be logged in if they wanted to use the old Reddit interface. Reddit doesn't specify what the changes to old Reddit will be, but Kim says the company is "exploring different options" and notes that "in the short term we will limit access to logged-in users and migrate critical bots and moderator workflows."

Old Reddit could be the next casualty of Reddit's war on AI scraping - Engadget

Old Reddit, the 21-year-old desktop version of the site still preferred by many longtime users and moderators, could become the next casualty of Reddit's war against AI scraping. The company is warning users that it plans to make unspecified "changes" to the legacy experience. In a blog post, the company said that changes are necessary "in order to protect our platform, business, and users from abusive scraping and spamming." Mysteriously, the company doesn't indicate exactly what changes it has planned, though it says it will "work on migrating critical bots and moderator workflows to our modern stack." Reddit said at the end of June that it would block access to Old Reddit if users aren't logged in. "Old Reddit's logged-out experience is a significant source of abusive scraping and automated traffic on the platform," Reddit admin boat-botany shared at the time. So far, it seems that this particular change hasn't fully gone into effect. At the time of this writing, I was able to access Old Reddit without being logged in, but was later met with a message that it has been "blocked by network security." A Reddit spokesperson said the change is happening "gradually." While Reddit doesn't indicate what its long-term plans for Old Reddit might entail, the fact that it's trying to move bots and moderation infrastructure away from it, is sure to raise questions about how long the company will continue to support the older version of its site. The company has already hinted at the possibility Old Reddit could go away. In a comment on the post from boat-botany last month, the Reddit admin wrote that "we can't promise it will be around forever." When asked by Engadget if the company was planning to shut down Old Reddit entirely, a spokesperson for the company didn't answer directly. She said that the company is "exploring different options" for Old Reddit. "We don't have a hard timeline right now, but we will work directly with the mods, developers, and communities that depend on our systems and make sure to keep everyone updated," she said. Reddit has taken increasingly aggressive measures to fight AI scraping and unauthorized use of its data. In 2023, the company began charging for access to its API, citing concerns that its data was being used to train large language models. That change effectively killed third-party Reddit clients which prompted a site-wide protest. Now, Reddit says it will begin to phase out its API entirely. The company will "continue supporting limited public API access" but "will gradually restrict new requests and require third-party apps to transition to and operate on Reddit's Developer Platform." Reddit's Developer Platform, also known as Devit, lets developers build bots and other experiences on top of Reddit but is more tightly controlled than its API. The company has already been offering incentives, including a $1 million "app migration program," to get developers to make the switch. Now, it's clear that developers won't have a choice. It's not clear whether Reddit will continue to offer API access to select researchers. The company also shared that it's overhauling its moderation infrastructure. Reddit's expanding tests of its LLM-based moderation system, Rules Hub, which allows subreddit moderators to control how rules are enforced. According to Reddit, Rules Hub is an improvement over the longtime AutoMod system because it's able to "to better handle nuance, natural language, and edge cases" since it can interpret the "intent of a rule" rather than relying on keyword matching. A Reddit spokesperson said the company's goal is for Rules Hub "to eventually replace the AutoMod enforcement capabilities" but that "all other aspects of AutoMod will remain."

Reddit is letting AI decide when your post breaks the rules

The optional tool is rolling out more widely later in 2026, following testing in over 700 communities. Reddit moderation has never exactly been a polished operation. It runs on volunteer moderators, user reports, and Automod rules that may have been written years ago by someone who has since vanished from the subreddit. Perhaps inevitably, AI is now also being invited behind the scenes at Reddit, with a new system that can decide whether posts and comments should be reported or removed. As The Verge reports, Reddit's new Rules Hub uses large language models to judge whether content matches the "intent" of a subreddit rule. Automod usually looks for specific words, phrases, or patterns, while the new system is meant to understand context and handle messier cases that don't fit neatly into a keyword filter. Moderators will still write the rules and decide what happens when one is broken, but Rules Hub can be configured to send content to the mod queue, filter it, or remove it automatically. Mods can also test rules on older posts before switching them on and inspect logs to see why the system took action. That means humans are still technically in charge for now, but it also means an AI could become the first thing to judge whether your post was a joke or an insult. And moderators willing to trust the LLM's judgment can let it junk your posts without human intervention. Reddit says Rules Hub has been tested over the past few months with moderators from more than 700 communities, including members of its Mod Council Network. It's now available for newly created subreddits and is expected to roll out more widely later in 2026. The company also says it isn't ready to replace existing systems in larger or more complicated communities. Reddit believes the Rules Hub AI could eventually take over many of the enforcement jobs currently handled by Automod when combined with tools such as Post and Comment Guidance and Safety Filters. So, human moderators aren't being replaced just yet; the machines are only helping to clear the mod queue. Whether the AI creep stops there remains to be seen.

Reddit is replacing Automod with AI that reads intent, not keywords. Old Reddit's days are numbered.

Reddit plans to replace Automod with LLM-powered Rules Hub, restrict public API access, and eventually phase out Old Reddit. 130M daily users, 100K+ communities. Changes roll out over months. Reddit announced plans to replace core moderation infrastructure that has run the platform for years. The most significant change: Rules Hub, a new moderation system that uses large language models to evaluate whether posts and comments match the intent of a community rule, will eventually replace many of Automod's enforcement workflows. Unlike Automod, which relies on exact keyword and pattern matching, Rules Hub can handle nuance, natural language, and edge cases. It has been testing in over 700 communities and will now be available to all newly created ones. The platform is also restricting public API access further. Third-party apps must transition to Reddit's Developer Platform, and new API requests will be gradually restricted. Reddit launched a $1 million migration programme to help developers move. This follows the 2023 API pricing changes that killed popular third-party apps like Apollo and triggered a site-wide protest. The new restrictions complete that transition: all trusted automation will eventually run within Reddit's own ecosystem. Old Reddit, the 21-year-old legacy desktop interface, will face "complex follow-up steps" beyond the current login requirement. Reddit framed the changes as anti-scraping measures, but the language signals that Old Reddit's unrestricted access is ending. Google replaced its traditional search with AI summaries and faced a backlash from users who preferred the old version. Reddit is making the same kind of forced migration, replacing a system users chose with one the platform controls. Reddit now has over 130 million daily visitors across 100,000+ communities. The LLM-powered moderation is the most technically interesting change: if Rules Hub works as described, moderators set rules in plain language and the AI enforces them contextually, reducing the regex-writing and keyword-list maintenance that Automod required. Wharton researchers found people accept AI outputs 80% of the time, and the question for Reddit is whether moderators will trust an LLM to interpret their rules correctly, or whether AI-powered moderation creates a new class of false positives that are harder to understand and appeal than a keyword match.
