Sure, having a 100% reliable system is impossible as you have laid out. However, if I understand the announcement correctly, this is about volume, and I wonder if you could have a tool flag articles that show obvious signs of LLM usage.
The point is that this leads to an arms race. If Arxiv uses a top-of-line LLM for, say, 20 minutes per paper, cheating authors will use a top-of-line LLM for 21 minutes to beat that.
