One of Reddit's main open-source forums has closed its doors to artificial intelligence — and to a large share of the people who write software. The moderators of r/opensource, a community of 392,000 members, posted a new set of submission rules on Saturday, October 24, under the title "Your tokens aren't valuable: No more AI."

The headline rule is absolute. "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," wrote moderator Wolvereness. "AI, as it exists today, is incongruent to this Open Source community."

More than an AI ban

The AI clause is only part of the overhaul. Projects shared in the forum must now be at least a year old and actively maintained, have multiple contributors — "subjectively 3+" — an existing community, and an OSI-approved licence. School-style capstone projects such as note-taking apps, PDF viewers and command-line music players are out, and so are tools built for AI, with MCP servers — the plug-ins that connect chatbots to outside software — named as an example. Requests for maintainers or contributors are no longer fielded either.

Posters must also hold accounts at least a year old "with significant Reddit contributions" — and appealing a removal in modmail earns a permanent ban and mute. Wolvereness estimated "20 messages a day from people expecting their slop projects and burner accounts to get an exception."

The language rule has drawn some of the sharpest objections. "If you don't speak English, you need to find a different community," the post reads. "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." Critics say the clause punishes developers working in a second language — the lifeblood of open source.

The backlash — and a rival forum

The reaction was immediate and hostile — enough that a rival subreddit, r/trueopensource, appeared within a day. The top comment on the rules post read: "This is orthogonal to open source. It's OK to not like AI but it doesn't change whether something is open source or not. I guess Linux is no longer allowed here? Linus uses AI for kernel development now." Open-source pioneer Linus Torvalds announced earlier in October that he had used Claude Code to write for the Linux kernel.

Wolvereness stepped into the comments to argue there is room for nuance and selective enforcement, citing software that "incidentally has accessibility features that use AI," such as automatic captioning. The moderator also blamed the flood of criticism on outsiders drawn in by an opinionated editorial post, noting that many of the top comments came from users who had never posted in r/opensource before. Some members, though, cheered the end of low-effort "slop" posts drowning the forum.

Why the ban may be impossible to police

The deeper problem is enforcement. AI coding tools are now woven into everyday development, so a rule that bans anything AI touched arguably excludes projects as big as the Linux kernel, Chromium, Firefox and VS Code — a list that circulated widely on X after the announcement. Either moderators enforce the letter of the rule and shrink the forum to an island of hand-written code, or they enforce it by judgment, case by case — which critics say the accessibility carve-out already admits.

For now, r/opensource has made itself an outlier: a community built on openness, drawing a hard line around modern software's most widely used tool — and finding the line harder to draw than to announce.
