I have an idea about how we can detect cheaters more easily.

We can create an extension or an automated system that checks submissions of each contest. The system can compare the codes with GPT, Claude and Gemini to find submissions that look very similar or suspicious. If the system finds a suspicious submission, it can automatically send it to the admins for checking. The admins can then decide if the user is cheating or not.

I think this system can help us find many cheaters and make contests more fair. Of course, it may sometimes make mistakes, so the final decision should be made by the mods.
