Use this for anything related to plagiarism - Reporting cheating, appeals, etc

I believe this topic is oversaturated now. Before and after every long challenge someone says the same thing you said. Probably when the MOSS will catch plag by say 2023-2024 of 2020 contests most of the people will have left Codechef. Actually blame those youtubers who say CP is gateway to FAANG etc are the rootcause of this problem.

targer_5star If I were a specialist, last thing I’d do would be bragging about it. Many masters don’t feel confident in their skills, let alone experts/specialists. The only more confronting thing could be talking about securing rank 1 in a 30 people piece of cake competition. You’re violating the rules if you share your code or use the shared code, so it doesn’t matter whether you cheated or not, I won’t be getting into that, though there’s a lot of evidence against you. Don’t try playing a victim here, you’re just ruining your own reputation and becoming less trustworthy. That’d be my 2 cents.

Everybody knows the LONG challenge has become the hub to cheat and earn ranks but recently the Cook-off’s aren’t also safe. After many wrong submission, I was able to solve few questions in COOKOFF july but after the contest ended I came across a youtube channel which was sharing the codes of the current COOKOFF questions(within the contest timings). Please we 3 star or above rated coders get only 2 contests in a month to have a chance to increase our ratings, don’t sabotage that too.
Please report the youtube channel Youtube Channel Link. There are many more such youtube channels which I can never search up to but please don’t make the cook-off unrated too.
This is a request to all those code sharer’s and video makers, please don’t destroy the decorum of these contests and force others to leave Codechef.

Hey Guys ! Today I came across two profiles of Div 3 and I think ( I again say I only think, not sure abt it ) , they are cheating in Aug Long Challenge 2021. Means one user riyaa_03 has started today and solved 9 questions in one go. All their submissions are within time range of 1 hour or even lesser. How anyone can do that I am just surprised.
Another one is india_no_1 . His also 1st contest but has solved all 9 questions.
This cheating shit is becoming terrible. Codechef needs to take care of this thing otherwise the honest persons in CP would surely leave Codechef.
@admin please see to it.

@admin please take a note of this. Have gone through their solutions personally and they exactly similar. Very demotivating.

amitkarmakar13 · August 16, 2021, 5:13pm

It seems there was massive plagiarism in August Long 2021 Contest.
It is very easy to spot plagiarism in the solutions of the following users. (See solutions for GEO1, FATHUT, CHARGE, CDIGLNUM). And these are like the top 20 ranking users in the contest.

Cheating spoils the fun for everybody else. As we see the top 20 ranking solutions are plagiarised, this seems to be a major problem.

I understand it’s a difficult problem to solve(the plagiarism) but I hope codechef does something to remedy this post contest.

dev_202 · August 16, 2021, 5:46pm

@amitkarmakar13 :
Exactly. No point of making a contest if such malpractices are used to get top rank and not get punished.
@admin please take note and do something to curb such plagiarism.
Plagiarism check must be done especially for long challenges like this.

mak29 · August 16, 2021, 5:51pm

It’s saddening!
Plagiarism should be stopped.

I found a bunch of people from the same college copying the exact code from a youtube video with the solution in it. The video was published during the contest

ARRFILL (Only difference is the capitalization of variables)
thelordsaurabh - CodeChef: Practical coding for everyone
mayank_46 - CodeChef: Practical coding for everyone
ravish_29 - CodeChef: Practical coding for everyone

The video they copied from : - YouTube
( Kindly note that the link is set in such a way that it takes you to a specific time when opened. I have done this so that you wouldn’t have to go through the whole video to search for the code)

Two of them have the exact same code for CHARGE as well
thelordsaurabh - CodeChef: Practical coding for everyone
mayank_46 - CodeChef: Practical coding for everyone

Please look into this as they have boosted their rating to the mid-3 star level because of this malpractice, I have sent help@codechef.com a mail as well.
Thank you

waltzer47 · August 22, 2021, 7:17pm

Most of the submissions for CLOSCHEF and CLEARRR in the last hour are identical. Hope @admin will do plag checks before rating updation.

gamma30 · August 22, 2021, 7:30pm

is plag check even a thing here on codechef?
