An ICML reviewer discovered that every paper in their assigned batch contained hidden prompt-injection text embedded within the PDFs.

This appears to be a secret compliance check by the conference organizers to detect if reviewers are using LLMs, which is strictly forbidden under the conference's Policy A.
