SLIPPERS solution for all these accounts is plagiarised and is same.
There are even more.

Snackdown Ranklist in a joke everyone very easily did two problems. This makes it so hard for anyone to qualify. Sadly this is what codechef is like and we have to live with it.

sourabh_0123 · November 22, 2021, 3:31am

I have mailed several time got a reply that they will be running moss soon.
But nothing really happened.

sourabh_0123 · November 22, 2021, 3:33am

In November Cook-Off 2021 Division 2 there was mass cheating in question 3 and 4 .

One can easily see that last 20-30 submissions specially have same main function() code , even with naked eyes someone can conclude that it is copied.

Please compare some of the below

Just checked the rankers from 501 to 545 and the number of same code i have seen is so many

yaminote · November 22, 2021, 9:05am

Wth is that like 30 people among 45. Insane. I was totally demotivated seeing everyone solving a second problem while i was stuck getting WAs lol. Sad though at this rate codechef rating will not remain credible either.

sourabh_0123 · November 26, 2021, 6:33pm

I am sick for this ppls i always report them but here they are cheating once again in fuzz

Mails arent ignored,

anon43275151 · November 27, 2021, 8:51am

yesterday I mailed around 30 users who have the same code of 5th problem div2 cause all solutions are the same, as I was not able to solve problem 5 so I was checking how someone attempted this problem but all have the same solutions.

sourabh_0123 · November 27, 2021, 5:00pm

me observing my rank goes from x to x+(200 to 250) in last 10 min.

fireship · November 27, 2021, 11:33am

Please Codechef run plagiarism tests for at least once… Please Please Please Please Please Please

It’s simply not fun to participate in your contests anymore

ATLEAST BAN THE OBVIOUS COPY PASTE SOLUTIONS !

JUST RUN PLAG TEST ON ONE CONTEST AT LEAST

I DONT DESERVE THIS ! WHY ARE U DOING THIS TO US @admin

realnikhilnaik · November 27, 2021, 12:05pm

Even i dont remember when was the last time Admin even replied to plagiarism concern

fireship · November 27, 2021, 1:40pm

Sometimes it feels that Codechef lowkey wants this, because

more cheaters == more traffic

they are simply a money making website, who doesn’t care about their users anymore.

gultai4uk_r · November 27, 2021, 9:06pm

Pre-Elim passed and nothing was done!

ssvb · November 27, 2021, 11:05pm

Yes, CodeChef promised to do plagiarism check within a week after SnackDown 2021 - Online Pre-Elimination and permanently ban cheaters from the platform. This hasn’t happened yet, but there’s still technically 1 day left until the promised deadline. And I’m not very much concerned even if they miss the deadline by a few days. As long as the plagiarism check actually gets completed before the next SnackDown round.

Based on this chart (originally posted in a comment on codeforces by @aropan), there was a clearly visible group of around 300 cheaters in SnackDown 2021 - Online Pre-Elimination (the number of actual SLIPPERS at the end of the contest minus the number of expected SLIPPERS if we look at the chart up to 2:24:00 and extrapolate).

gultai4uk_r · November 27, 2021, 11:51pm

Check actual comment to which I replied and a comment above it.
You will see that it was a reply to a promise to perform plagiarism checks for Codechef Snackdown Round-1A (where we had massive cheating going on) before Pre-Elimination Round. I have found this comment (and thread) today and decided to bring it up again (like I did here) because in both cases plagiarism checks were promised to be done before Pre-Elimination and they didn’t!

As for Pre-Elimination plagiarism checks I’m also perfectly fine to wait more than one day if they will be done properly. Moreover, I’d rather have Elimination Round postponed because of this issue than to have all these cheaters participating in it. Moreover, if CodeChef cannot do that properly by themselves - I and maybe few more interested/annoyed by a cheating people from a community would be able to help with that by at least reporting cheaters who are gonna pass to Elimination Round otherwise or even by improving their anti-plagiarism software (if there will be enough time to do that).

I am not 100% sure but I see some similar solutions for Sorting Segments , I strongly believe this round is also cheated by people
