We can observe that in https://mirror.codeforces.com/contest/2228/submission/374794092 and https://mirror.codeforces.com/contest/2228/submission/374792764 This person wrote completely different code every minute. Obviously trying to use AI.
The username is not concealed. The code is also very similar to AI
For example, this: https://mirror.codeforces.com/contest/2228/submission/374855188
https://mirror.codeforces.com/submissions/dreaming123
This person submitted multiple completely different codes for the same question in a short period of time, obviously using different AI to constantly try.
https://mirror.codeforces.com/contest/2228/submission/374790069 https://mirror.codeforces.com/contest/2228/submission/374791605
The code is vastly different in just one minute.
By the way, I don't know why the message 'Page is temporarily blocked by administrator' appeared while searching for submission records, and the system suspects that I am a web crawler. That's ridiculous.
Due to this reason, I am unable to continue my investigation
