around 1 week.
sometimes it can take even longer because they receive a large ammount of mails.
Itâs ok if they respond a little late, but the appeal period is only for 6 days so i am quite worried.
Anyways, thanks for helping.
This Guy https://www.codechef.com/users/ac_rusher never stops cheating this would be his 7-8th id which he has created in the span 3-4 months
Here are all the codes that he copy pasted and look at the technique he is using to avoid plag he is copy pasting approx 100 lines of commented code between every 3 to 4 lines of normal code @admin does the plagirism check fails in this case? if not please punish as per required @shaily_adm

Yes, this plagiarism check fails where it should work.
It works only for problems rated below 800 which have 2 lines of code logic where innocents get plagiarised [i m one of them 
] .
Such a big platform but still lacks proper anti-plagiarism mechanism and they donât even respond in mail.
There are 250+ submissions in div 4 starters 39 with the same code for the minimize roadblock problem, this is so unacceptable and unfair for others who donât cheat and get less rank because of them. Many just change variables or insert random comments or functions between the actual code. No plagiarism for them?

same was the case of div 2
wow you ranked 304? good job being that fast. You would have been top 50 without the cheater xD
It is completely crazy that more than half of the top 1000 are cheater in every Div4 contest.
I participated in this contest: Contest Page | CodeChef (Div 4)
The last problem was hard for me, even though I am experienced. What shocked me is that roughly 150 people solved the problem in the last 20 minutes. So I went checking. Rank 303 is the last who solved P7. Rank 303 - 284 have the same answer and are therefore cheats. I had to check 20 people to find the first legit participant.
I also checked the top participants for cheats, I had to check the top 9 to find the first cheater and most likely the source creator for all other cheater.

Hello everyone!
Four days ago, I got a mail about my submission being similar to someone else.
Here are both submissions -
https://www.codechef.com/viewsolution/63768420
https://www.codechef.com/viewsolution/63786485
As you can see the question is very easy and has one line solution. Two people can have the same code. It was just a coincidence. This is a case of false positive. I replied to the mail and requested a manual review but didnât get a reply.

Recently long challenge may 2022 ended and there was so much cheating involved I solved according to my capability but still my ranks are decreasing like waterfall, how can div4 people with a new account and giving first contest can solve all questions and on last day there are exponential increase in submissions of 6,7 and 8th problems. So bad to see all this people selling solutions and it doesnât.
Stop conducting long challenges instead conduct 3 short challenges of 1.5hrs for 3 days so that no one can cheat.

yes, that is true, but few of the many accounts that solve all the questions are alt accounts of coders who are way more skilled that do not belong to div 4.
why they are not responding for my appeal against false plag check
i submitted a sol which was WA in start34B then i didnt try to submit anymore i skipped that contest and for that my rating already fall for that contest but then they plag my code and decreased my rating by -315?
Like WTF is this
they are not even responding my mails
Kindly check your inbox/spam for this email having the subject line âCodeChef - You have been caught for plagiarism inâ along with the contest code and follow the instructions given there. The appeal phase will happen in the original plagiarism email thread.

Omg this admin is OP. Really glad to see codechef taking action.
I have just one question : Do honest coders rating would get updated ? ( these cheaters have given great damage to the rating of ours ; we should get what we deserve . ) I believe in the supremacy of this new admin
