I submitted the code 294052353 during 2034D - Darius' Wisdom, and today I received a penalty notification. It stated that my code is identical to that of Kanha_Madan123, Im_the_real_God_Coder_KM, Wali05, and encernwala. I did not share my code with anyone. I suspect that these four individuals are from India (the first two mentioned their nationality on their profiles), and one of them likely accessed my code through the post-solution hack feature after solving the problem and then shared it with the others. I believe this inference is reasonable, as there have been numerous blogs on CF highlighting such behaviors by some individuals from India.
For example:
Why is there so much cheating in Contests in India ? Especially on CodeChef?
And many others.
Based on the above, I don’t think I should receive this penalty. Could you please revoke it?
The four records above are the submission histories of these four participants.
