The moderators of r/opensource, a Reddit community created on January 25, 2008, posted a policy on October 24, 2026 that bars any project which uses artificial intelligence, is made by it, or is intended for it. The post, titled "Your tokens aren't valuable: No more AI." and pinned by moderator u/Wolvereness under the Discussion flair, also introduces a set of minimums for every project advertised in the forum: one year of active maintenance, roughly three contributors and an existing community. It drew about 1,400 comments within a day, and its net vote score stood at zero.

ELI5

A large Reddit forum about free, open software has decided it no longer wants posts about programs made with AI tools, or programs built to work with AI. You'll also need an older account and a project that has been around and maintained for at least a year before you can show it off there. The change has split the forum, with many users cheering the end of low-effort "slop" posts and others arguing the rule would technically exclude projects as big as the Linux kernel.

What the moderators wrote

The post opens with a single sentence summary. "The long story short, if your project uses AI, is made by AI, or is intended for AI, it's not welcome on r/opensource," according to u/Wolvereness. "AI, as it exists today, is incongruent to this Open Source community."

Five enforcement criteria follow. The first concerns projects. "Projects advertised here must be all of: 1 year old (not just age, but actively maintained), have multiple contributors (subjectively 3+), not be a common capstone project (school projects, such as note-taking, PDF viewers, cli music players, etc), not be intended for AI (such as MCPs), and have an existing community," the post reads. The reference to MCPs points to servers built on the Model Context Protocol, the interface that lets AI assistants call outside tools and data, which the moderators place squarely outside the forum's scope. The post adds that the community will no longer field requests for maintainers or contributors, and that an OSI license remains mandatory "as it's always been."

The second criterion applies to people rather than code. Accounts must be at least one year old "with significant Reddit contributions." The moderator was blunt about appeals: "If you send us a message in modmail about this after having attempted to post, you will be permanently banned and muted. If this seems harsh, know that I estimate 20 messages a day from people expecting their slop projects and burner accounts to get an exception."

Third, the post addresses visible AI use directly. "If it's obvious you're using AI in your project, we don't want it. Tokens are cheap, and we don't care how many you spent to make your amazing project." The phrase gives the post its title. Tokens are the units in which large language models process and bill text, so the line is a dismissal of the compute spent generating code rather than a technical claim.

Fourth comes a language rule. "If you don't speak English, you need to find a different community. We cannot distinguish between AI-written and AI-translated. Since you don't speak English, you can't even verify yourself if it translated correctly."

The fifth criterion is about punishment. Temporary bans are reserved for members who "made temporary lapses in judgement, such as when getting agitated." Anyone who posts or comments "the result of your LLM output tokens," according to the post, "will never be welcome back."

Exemptions and the cleanup crew

There is one carve-out. Organisations "officially incorporated under 501(c), or (d) (e) (f) (k), or 521(a), or the equivalents in their country" are exempt from both the project and the account minimums, provided they contact the moderators and are approved before their first post. The moderator stressed that the exemption is not limited to 501(c)(3) charities, "purposefully so." The post also invites volunteers to join a "cleanup crew," and suggests that anyone opposed to "keeping this community for the humans" try r/opensourceeai, a name the moderator flags with "(sic)."

A later edit to the post acknowledged a breakaway forum. "/Edit: shout out to u/esk6plays for starting r/TrueOpenSource. Let's cheer them on! Hopefully it will be an great refuge for those affected by this policy."

Size of the forum

The community sidebar shows 98,000 weekly visitors and 2,100 weekly contributions. It describes r/opensource as "A subreddit for everything open source related," taking its definition of open source from Wikipedia. Four moderators are listed on the page: u/Wolvereness, u/ssddanbrown, u/ShaneCurcuru and u/NatoBoram. Eight standing rules sit alongside the new policy, among them "No Spam or Excessive Self-Promotion," "No Drive-By Posting / Karma Farming" and "No Link Aggregations."

The Linux kernel problem

The sharpest challenge in the replies came from users asking how the policy treats the Linux kernel, the largest open source project by most measures. User u/NounverberPDX asked whether the kernel, "which has apparently embraced AI-assisted contributions," was covered by the nonprofit exemption through the Linux Foundation, counted as an edge case, or was now off-topic.

u/Wolvereness answered under the moderator badge. "Linux Foundation would be exempt from account minimums. The Linux kernel would obviously pass the project minimums." On the AI question, the moderator wrote: "Is the Linux kernel obviously the result of AI tokens? I think, on the subjective line, it would be allowed."

That answer did not settle the matter. u/LambdaCake replied: "Then your wording is nonsensical, because apparently they use AI, just in a way you like." User u/David_AnkiDroid quoted the policy's "if it's obvious you're using AI" sentence against the kernel's own documentation, writing: "The Linux Kernel doesn't pass this bar as written." The comment quoted the kernel guidance: "When AI tools contribute to kernel development, proper attribution helps track the evolving role of AI in the development process. Contributions should include an Assisted-by tag in the following format."

That guidance sits on the AI Coding Assistants page of the Linux kernel documentation. According to the page, contributions made with AI help should carry an "Assisted-by" tag naming the model and any specialised analysis tools, AI agents must not add the Signed-off-by tag that certifies the Developer Certificate of Origin, and the human submitter takes full responsibility for reviewing the code and its licensing. In other words, the kernel does not hide AI use - it records it in every relevant commit, which is the opposite of what a rule keyed to "obvious" use would seem to tolerate.

Other users took the same line with less patience. u/Termin8tor wrote: "Tell that to Linus Torvalds. Is this sub planning to stop posts about new Linux distros or kernel releases? Torvalds himself is using LLM tech after all for mainline kernel code." u/jameson71 asked whether the policy meant "no talking about the Linux kernel in here?" and u/dancingwithlies wrote: "reddit runs on Linux. Which now has AI contributions. Therefore, r/OpenSource has to delete itself."

u/esiy0676 linked to a separate r/linux thread titled "Linus Torvalds shares his thoughts on anti-AI" and wrote that Torvalds "called it effectively 'idiotic' - yes that's an actual quote." The linked thread is itself a Reddit post, and the quotation attributed to Torvalds could not be checked against a primary source in the r/opensource discussion.

Support for the policy

A large share of replies welcomed the change, and the comments with the highest visible scores were supportive. u/rectl, at 24 points, mocked the posts the rule targets: "Oh no! we are all gonna miss the daily 'i built a dynamic island-craft alternative on windows for 9.99$ subscription, open source btw' cross posts from r/vibecoding such a shame." u/InsideResolve4517 wrote "good move" and asked the moderators to add a mod label to the post (21 points). u/jkubic posted "Great decision. I'm so tired of slop projects" (14 points), and u/After-Peace-4734 called it "a step in the right direction" (11 points).

The more detailed defences focused on the age requirement. u/AndThenFlashlights described it as "a good low-pass filter for both the symptom and the harm of low-effort vibeslop." The same user added: "So many 'I got tired of ___ so I made ___ and we're looking for testers' posts are for repos with a week or less of existence, usually without any real-world testing or sane unit tests. And they usually duplicate existing functionality of long-standing FOSS projects. They're looking for free labor from the community that they're ripping off, before even validating their idea."

u/Omer-Ash expressed the hope that "other subreddits follow suit one day," adding: "I'm sick and tired of these 'I wanted X, so I made Y' slop posts." u/mind_captivator wrote that opponents "apparently haven't seen the constant barrage of slop coded apps that have been pummeling the subreddit for months now." The phrase that keeps recurring - slop coded, vibecoded, vibeslop - refers to vibe coding, the practice of building software by prompting an AI model and accepting its output with little review.

Some support came with reasons beyond code quality. u/RebTexas wrote that generative AI "is built on thievery" because "Both image and text/code generation is based on datasets obtained without the original authors' permissions."

Objections

The critical replies fell into a few groups. One argued that the rule confuses tools with outcomes. "It shouldn't matter. If it's open source code software then it's open source code software," u/AlliedR2 wrote, comparing the rule to a car forum banning cars built with robots. u/Max-_-Power likened it to "saying 'if you use an IDE, autocomplete or use search engines or StackOverflow for finding out how to do things it's not by you.'" That comparison was rejected in turn by u/gbrlsnchs: "No this is a really disingenuous point and it drives me insane. AI is not 'just another technology'."

A second group took issue with the non-AI minimums. u/aes110 said the AI ban was something they supported but called the age and contribution requirements "a bad rule though. This is a place to share projects, mostly new ones, which can also introduce new contributions from the community." u/micseydel described a personal project, more than two years old, MIT licensed and actively maintained, which "uses Whisper (optionally) but not generative AI" and still "can't be 'advertised' here," while adding: "overall I'm happy with this change." u/R4ndyd4ndy agreed with the maintenance requirement but argued that "the other criteria are way too broad," warning that defining rules broadly and enforcing them selectively "would have too many similarities with how autocracies govern themselves."

A third group objected on principle. u/Ungreon wrote that the policy "is just giving up dressed up as a principled decision," and argued that "The rise of CVEs has shown us that current opensource needs to level up," calling for shared ways of raising standards "Not blanket gatekeeping because it is difficult." u/Drakonis96 wrote that open source "is about freedom not gatekeeping developers based on the tools they use, the language they speak or how many contributors they have." u/DavidBevi argued that the moderators "should start r/opensource-subset without driving others to need r/TrueOpenSource."

The language rule drew a long correction from u/Shoddy-Childhood-511, who agreed that "LLM written text should be banned" but disputed the claim that AI writing and AI translation cannot be told apart, describing the manual process of checking machine-translated text. u/Wolvereness replied: "The biggest reason for this is that the quickest quip back when someone is obviously using AI is that they just 'translated' it."

User u/aflamingcookie pointed to the platform itself, writing that "reddit uses ai extensively," including for content moderation. And u/AliceCode warned that the thread was "likely" being brigaded, having found it through another post complaining about the policy. The moderator's reply: "Oh yeah, well aware."

Reading the numbers

The visible figures on the page are limited, and they point in different directions. The post's net score of zero after roughly 17 hours, alongside about 1,400 comments and seven crossposts, indicates a split audience rather than a consensus. Reddit displays net scores, not raw upvotes and downvotes, so the zero conceals the size of each side. The highest-scoring comments shown were supportive, yet the comment view was sorted by "Controversial," which surfaces contested replies first, and many supportive one-liners sat at zero or below. With a moderator acknowledging possible brigading, neither the vote total nor individual comment scores can be read as a measure of the regular community's view.

Several parts of the policy rest on subjective judgement by the moderators' own description: "subjectively 3+" contributors, an "obvious" use of AI, and the Linux kernel being allowed "on the subjective line." The post gives no definition of when AI use becomes obvious, no process for appeals beyond nonprofit pre-approval, and no date on which the rules take effect, though the wording ("We're going to be implementing") suggests enforcement is imminent or under way. The figure of 20 exception requests a day is the moderator's estimate.

Why this matters for marketers

Reddit communities are governed by volunteer moderators who can set rules far stricter than the platform's own. Reddit took a different approach this year. In March, the company said it would label permitted automation and remove around 100,000 bot accounts a day, without setting a sitewide rule on AI-generated text; its focus was on whether a human stands behind an account. r/opensource has gone further than that, targeting the output itself and the tools behind it. In June, Steve Huffman wrote that the platform's models block up to 23 million spam views a day and argued that "the rest of the internet is filling up with synthetic content" - the same pressure the r/opensource moderators describe at the level of a single forum.

For marketers who treat Reddit as a source of organic reach, the rule is a reminder that community-level policy can close a channel overnight. Developer tools, ad-platform connectors and AI integrations are the products most directly affected. Google released an open source MCP server for the Google Ads API in October 2025, and projects of that kind - "intended for AI (such as MCPs)" - are now explicitly unwelcome in one of Reddit's main open source forums, whatever their license or maintenance record.

The debate also mirrors one already running on the advertising side. PPC Land described what AI slop is and why advertisers should care in January, and brand safety vendors have since built products to avoid it; in October, IAS said brands could block YouTube ads beside AI slop. r/opensource is applying the same instinct to a community rather than an ad placement.

Questions about the provenance of AI-generated code are not confined to Reddit either. In September, the Ninth Circuit affirmed the dismissal of a DMCA claim against GitHub and OpenAI over Copilot's output, leaving the training question unresolved. And research covered in January found that experienced developers keep tight control over AI coding agents, reviewing changes and handing agents only a few steps at a time - a working pattern closer to the Linux kernel's disclosed, human-certified approach than to the one-week projects r/opensource moderators say they are trying to keep out.

Earlier in the year, Tailwind Labs cut three of its four engineers after founder Adam Wathan said revenue had fallen close to 80% as developers generated Tailwind code with AI assistants instead of visiting its documentation. That episode showed one cost AI coding imposes on open source maintainers. The r/opensource thread shows another: the time volunteers spend filtering what AI makes easy to produce.

Timeline

Summary

Who: The moderators of r/opensource, a Reddit community with 98,000 weekly visitors, led by u/Wolvereness, along with the users who replied and u/esk6plays, who started the breakaway r/TrueOpenSource.

What: A policy barring projects that use, are made by, or are intended for AI, with new minimums of one year of active maintenance, about three contributors, an existing community, an OSI license and a one-year-old Reddit account, plus permanent bans for posting LLM output and an exemption for incorporated nonprofits.

When: The policy was posted on October 24, 2026; the discussion continued into October 25, 2026, reaching about 1,400 comments.

Where: On Reddit, in the r/opensource community, with spillover into r/TrueOpenSource and references to a thread in r/linux.

Why: The moderator wrote that "AI, as it exists today, is incongruent to this Open Source community" and estimated 20 modmail messages a day from people seeking exceptions for "slop projects and burner accounts"; critics countered that the rule, read literally, would exclude the Linux kernel, whose documentation sets out how AI-assisted contributions must be tagged.
