It is because there are some private groups who leak the solutions and some youtube channels who share hints on the problems. To maintain the current rank , some users copy the solutions and that is why submission counts with most of them AC increases.

Long Challenges should be made unrated, otherwise Codechef ratings will soon become obsolete.

Yeah i am quite shocked as well as somewhat disappointed to see 300+ submissions of topological sort… i mean yeah that’s not Like an NP-HARD problem but still it’s quite hard and i am struggling from past few days to get 100 points but some people are doing like its nothing…

The accuracy of that topological sort question was less than the dense graph question for all the 9 days, on the last day, it suddenly reversed. No complaints, it happens always.

I don’t think it makes sense to only blame Long contests. Cheating is too prevalent in short contests as well.
Besides code sharing and code copying, there is also a concept of exclusive participation in short contests.
Meaning three or four people will make a group. They will divide the questions and will hence get 4x more time to solve as each person is solving 1-2 problem v/s 6-8. One month lunchtime will be submitted on User A codechef account, cook off on User B, next month’s lunchtime will be submitted on User C, next month’s cook off on User D account. And the above cycle repeats.
Have seen many people doing it. And will also pass plagiarism filters on coding sites.
As some questions in Long contests are too hard and distinguish good vs cheats, the same is rarely true in short contests where it is possible to divide and solve and average coders can score high.
I seriously doubt if Long contests are more fake than short.

I was searching for concepts related to questions and got interacted with a lot of answers of questions that too paid. Many people just to increase ranks do pay and get answer which I think is wrong. You just check everyone’s submission and you will see many submissions last minute.
That too the answer matches the one you see on youtube’s glimpse which is paid one but shows that yes this answer is working…
Just see this image and see the submission time and on seeing answer you see that they are the one you saw on YouTube videos which sell their answer.
Kindly make strict regulations as this makes our ranks down and in interview it matters what’s your rank in codechef too.
The one who is proved indulged in such should be given red star to his ranks showing cheating. My main motive is to stop this and whosoever is indulged doesn’t matter.
Plz codechef from last many challenges I am seeing this trend of increasing submissions at once just some time before ending. Plzz see this matter and red mark those ids indulged.

LOL they think codenation will just see their ratings and hire them… 
Yes, @anon39622507 who is cheating since december 2020 in long challenges hasn’t been penalized yet. He is submitting solutions in every language and changing variable names.

when you go to interview and if you have a good stars then that do matter .the main point is not rank or interview but cheating to those who dont do such things and seeing the submissions rate , they get disappointed on their skills too even though they are far better

“I was searching for concepts related to questions”-
Who searches for concepts/theory of problems on telegram 
. There’s youtube/wikipedia/cf blogs for that.
not telegram , google … youtube videos are there to sell . go search for it. dont do save them. this is a problem plz see as a problem instead
Its a responsibility we all have to take. Cheaters are always remain cheaters no matter how many rules and regulations have created. shame on those people who sell solutions for single penny
Why the long challenge is rated?
I would recommend this to be unrated, because many people post their answers on youtube, telegram and other apps too even before the contest ends which leads to the unfair means. Because most of the people who doesn’t even get the idea what the question is about, they are able to solve those questions too. This impacts the rating of other people who solved it genuinely.

This suggestion has been given many times nothing is going to happen. I personally like long contest. It’s a nice initiative but cheaters have made it look uncool.
