In the recently concluded CF Div. 2 competition, 7 out of the top 10 contestants have been identified as using AI to cheat. Even in my opinion, giperus's solution for problem E2, completed in just 15 minutes, doesn't seem to follow a human-like coding style.

These individuals were only caught because their rankings were exceptionally high. I wonder how many more contestants among the remaining participants also used AI.

Of course, those who were caught cheating simply fed the problem statements directly into AI and submitted the generated code without modification. If any of them had been smarter—by only reading the AI-generated approach and then writing the code themselves based on that idea—they might never have been detected.

In this era of explosive AI development, does the integrity of ratings in online competitions now rely entirely on contestants' honesty? Are we truly powerless to prevent cheating participants from dominating various online competitions?

Is there really no effective method to curb AI cheating at present? Will the ratings on platforms like CF, AtCoder, and Luogu ultimately become nothing more than "just for fun"?
