It's not a good time to be a program chair of a major conference:

21% of the peer reviews at ICLR (a major annual machine learning conference) were discovered to be entirely written by AI, and "more than half contained signs of AI use". This appears to be in violation of ICLR's terms of conduct, which "prohibited AI use that would have breached the confidentiality of manuscripts". The ICLR chairs write that they are planning to penalize reviewers who did this by desk-rejecting the reviewers' submissions but they say nothing about what they are doing for authors whose submissions received these reviews.
