TL;DR
arXiv has announced a policy that bans authors for one year if their submissions contain fabricated or hallucinated references. This move aims to enhance the reliability of preprints. The policy is newly implemented and details are still emerging.
arXiv has announced a new policy that bans authors for one year if their submissions include fabricated or hallucinated references, aiming to uphold the integrity of scientific preprints.
The policy was publicly shared via a tweet from arXiv’s director of technology, T. Dietterich, in March 2024. Under this policy, any author found submitting a paper containing hallucinated references — that is, references that are fabricated, incorrect, or not verifiable — will face a one-year suspension from submitting to arXiv. The policy applies to all categories of submissions and is intended to address increasing concerns about the proliferation of unreliable citations in preprints. arXiv has not yet disclosed the specific procedures for enforcement or how they will verify the authenticity of references, but the policy signals a firm stance against research misconduct in preprints.
Why It Matters
This development is significant because arXiv is a leading preprint server widely used by researchers across multiple disciplines, including physics, computer science, and mathematics. Implementing a strict ban for hallucinated references underscores a broader effort to improve research quality and prevent the spread of misinformation in early-stage scientific communication. It also sets a precedent that could influence other repositories and journals to adopt similar standards, potentially impacting author behavior and peer review processes.

Background
Concerns about fabricated or hallucinated references have grown amid the rise of AI-assisted research tools, which can sometimes generate plausible but false citations. Prior to this policy, arXiv had no formal sanctions specifically targeting reference accuracy, although the integrity of submissions has always been a concern. The move follows broader discussions within the research community about maintaining high standards for preprints, which often precede peer-reviewed publication. This policy is part of ongoing efforts to combat misinformation and ensure that preprints serve as reliable scientific resources.
“We are committed to maintaining the trustworthiness of the research shared on arXiv. The new policy on hallucinated references is a step toward ensuring the quality and reliability of preprints.”
— T. Dietterich, arXiv Director of Technology

What Remains Unclear
It is not yet clear how arXiv will verify the authenticity of references or how they will handle disputes or false positives. Details about enforcement procedures, appeals, or whether the ban applies to all authors involved in a submission are still emerging. Additionally, the impact on authors and how this policy will be communicated or enforced in practice remains to be seen.

What’s Next
arXiv is expected to publish more detailed guidelines on the enforcement of this policy in the coming weeks. Researchers and authors should anticipate increased scrutiny of references in submissions. Monitoring how the policy affects submission behavior and the incidence of hallucinated references will be a key focus for the platform. Further updates may include clarifications on verification methods and appeals processes.

Key Questions
What exactly constitutes a hallucinated reference?
A hallucinated reference is a citation that is fabricated, incorrect, or not verifiable, often generated by AI tools or through careless citation practices.
How will arXiv verify references in submissions?
Details are still emerging, but it is expected that arXiv will implement verification procedures, possibly including automated checks or manual review, before enforcing sanctions.
What happens if an author is banned under this policy?
Authors found submitting with hallucinated references will face a one-year ban from submitting to arXiv, during which they cannot submit new papers or revisions.
Does this policy apply to all types of submissions?
Yes, the policy is intended to apply across all categories of arXiv submissions, regardless of discipline.
Could this policy impact the quality of future submissions?
Yes, by imposing sanctions for false references, arXiv aims to encourage more careful citation practices and improve the overall quality and reliability of preprints.
