If you have been wrongly penalized in a CodeChef contest due to a mistaken plagiarism or wrong submission penalty, and you have written your code independently, you can take the following steps to request removal of the penalty:
- Contact CodeChef support directly by replying to the official email you received about the penalty or by writing to their official email address: help@codechef.com. Explain clearly that you wrote your code on your own and provide any evidence that supports your claim, such as timestamps of your submissions, your coding process, or differences in code logic compared to the alleged copied code5.
- In your communication, politely request a reconsideration of your penalty and rating drop, emphasizing that the penalty was applied incorrectly and that you have not cheated. CodeChef has acknowledged that false positives can occur and have processes to review such cases upon user request5.
