PlayStation 3 emulator RPCS3 devs battling "AI slop code pull requests"

The team behind the popular PlayStation 3 emulator RPCS3 have seen a rise in what they say are "AI slop code pull requests".

We've seen other open source projects face similar issues, the rise of AI bots and coding agents has caused waves of people submitting all sorts of random junk everywhere they possibly can. The Godot Engine team previously complained about the same issue, as have lots of others.

Writing on X the RPCS3 team said:

Please stop submitting AI slop code pull requests to RPCS3. We will start banning those who do without disclosing. There are plenty of resources online to learn how to debug and code instead of generating slop that you don't understand and that doesn't work.

In a follow-up post they additionally said:

Our guidelines for submitting AI-generated code are now up in our repository!

As for all the AI bros seething on our socials, we're simply blocking you.

Learn how to debug, code, and leave behind something useful to humanity when you're gone, instead of peddling slop.

They're not actually against AI code, but people submitting requests that are likely 100% AI generated without the submitters understanding what it does - or even worse, the code just being useless untested junk. Their new guidelines as stated on GitHub:

Use of AI tools for research and reverse engineering purposes is permitted. However, contributors are expected to fully own and understand all code they submit. Any communication with the team — including code, code comments, and GitHub comments — must come from the human contributor, not an AI agent acting autonomously.

We have unfortunately seen a rise in untested and unverified AI-generated slop being submitted to this project. This wastes maintainer time and, in worse cases, such changes get merged and break functionality for all users. Repeated violations will result in a ban from the repository. Please be respectful of everyone's time.

Pull requests opened by AI agents or automated tools must include a disclosure in the PR description stating the scope of AI involvement — which parts were AI-generated and what human testing or review was performed prior to submission. PRs that omit this disclosure may be closed without review.

If you are unsure about your work, open a discussion issue to talk it through with the team, or reach out to a maintainer on Discord.
