Cheaters that use chatgpt

I have come across multiple players using chatgpt during clashofcode battles.
How do i know it? when i saw that they submitted a code in 20 seconds, i copy-pasted the statement into chatgpt to get the exact same code. And for some reason i cant report anyone. (fe:neohr71 finishes every game in 20 seconds with answers from chatgpt)
We need to do something to prevent those players from cheating and ruining the game for everyone else! Maybe running the code through chatgpt and other knowns ai’s and check that the codes provided by players are different.
Feel free to share your experience with this and/or ideas to prevent it.
Thanks in advance for the feedback!
