My friend chennie got banned today for unknown reason. He did nothing else but just took part in ICPC 2026 Online Challenge 1 powered by Huawei and we cannot find out the reason why he was banned.
Here's his clarification:
I have never used AI tools, cheated, or received any external assistance in any official contest, nor have I ever violated community guidelines or posted any inappropriate comments.
Clarification on chennie_fan and chennie_negtive:
I noticed there are two accounts with similar handles on the platform: chennie_fan and chennie_negtive. I would like to clarify that neither of these accounts belongs to me.
They were created by my classmates as an inside joke.
Code Style: If you compare the submission code across these accounts, you will find significant differences in macro usage, variable naming conventions, algorithm templates, and overall coding habits.
IP Addresses: If the system or administrators verify the login and submission IP logs, it will be clear that these accounts operate from completely different network environments and devices.
The ban cost me over 6,000 RMB in prize money. However, what matters even more to me is this Codeforces account, which I have used since I first started learning competitive programming. It holds the history of my growth and so many precious memories.
Can anyone unban him? Or at least tell us the reason why he was banned.
