I also have a similar issue.
Please Sir, in search of finding the guilty don’t punish innocents.

I didn’t get any mail from codechef and without having any discussion they directly plagiarised me.
I mailed them my issue but till now didn’t get any reply.
Please, sir. It hurts a lot for those who are honest.
no 
How come others get your code during contest?
Hello admin of codechef
My handle is Hotdogcoding and i wonder how one of my contest I didn’t get any problem is [April Long One 2022, Division 4 (Rated)] when my global rank is 13594 how I still got plag for cheating?
I hope you can check it.
Hotdog,
Best regard.
Due to some technical issues, we have realized that many of the emails that we intended to send to users for plagiarizing in the 6 contests, as mentioned in the below table, weren’t received. Hence, these users did not get their appeal phase and had their ratings dropped before they could appeal their case. We sincerely apologize for that.
We are now resending those emails and are reopening the appeal phase for these 6 contests.
I can’t copy anyone’s program but why my point decreased due to plagiarism… : (

I have received a mail stating that I have plaigarised in CodeChef Starters 30 Division 1, Problem A. The solution of the problem is to sort a string and then print it. Now why would you even run a plaigarism test on such a problem is beyond me but the issue here seems to be that the template of both of the users is the same. My template is publically available with one of the sources being codechef’s submissions itself!(publically viewable after every contest). I expect that this will get cleared up.

Trust me. Div 4 innocents are suffering because of this non perfect plagiarism check.
I am one one of them. RIP START36D.
Hi all - I am new in codechef. I started doing contests around a month ago. Today i got a mail about my solution being similar to one other contestant. And yes i agree my code is somewhat similar. But the real issue is the problem in which i got plagiarised is a simple problem with direct approach with couple of lines of codes. Hence, chances of similar codes. So, in this case there should not be any strict plagiarism code of conduct.
START36D division 4, was my 2nd contest in codechef (1 star coder). I can’t actually explain much.
I just want to know how come there is zero possibility of few lines of code not being similar when there are around 10,000 users attempting it. I think that this Anti-Plagiarism should not be used for atleast Div 4 problems(mainly for simple codes) as there is high chances of similarities.
I have also replied The Chef in the mail about it. Hope i get justice. 
Below are the codes that got plagiarised. (my code and someone named @anon55306107 kt0601)

Buddy, i am currently in the same state where you have been earlier.
Check this post to know:
Innocents getting plagiarised START36D 2022
I want to know how you succesfully appealed and reverted the false plagiarism accusation. Please let me know. I have already replied to their plagiarism mail but didnt received any reply yet.
write a mail to codechef. i faced a similar issue so i mailed them, and they confirmed it was a case of false positive.
yes, i immediately replied(appealed) when i received their mail, but it’s been more than 36 hours, they haven’t replied back.
In your case, how much time did they took to reply/respond back?
around 1 week.
sometimes it can take even longer because they receive a large ammount of mails.
It’s 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 don’t 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 don’t 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.
