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.

Pre-Elim passed and nothing was done!

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).

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

Congrats! The admins did exactly what you asked and reduced the contest duration to 2:30 in December CookOff . The crowd of all these last minute cheaters arrived between 2:31 and 2:59 and they were very surprised to see that the contest is already over. Now their evil tricks can’t possibly work and the honest participants are happy to see that massive late submissions of plagiarized solutions are not happening anymore…

Oh wait, maybe that’s actually not the case. Could there have been some flaw in your logic?
