I also have a problem in decrease in rating as i did all the questions myself and just subitted my friends code in question RBTREE to chek the time limit but its unfair to decrease my rating as @admin can see that i had solved the question by my self before that submission so there is no point in decreasing my rating as i havn’t used any unfair means to solve that question as the points were achieved by me first only

One you blatantly stated that you asked for help. Two you stated that he did help you. Three you stated that one of you holds 2 accounts. AND THEN YOU STATE THAT YOU WANT YOUR RATING BACK. What irony!!! Whether you are a school student or a professional at Google, nothing gives you the right to ask and accept help during an ongoing contest. You should be happy that you haven’t been banned for a month or so.

Well my codechef account is showing no problems solved in nov14. While ranking still shows 419.3 points. And I coded each code by myself. All I want to know is it a technical glitch because I did nothing wrong on my side.

I did not copy someone’s code. I think asking to find a minor bug is not plagiarism. It means ‘the practice of taking someone else’s work or ideas and passing them off as one’s own’.

Good news, rating is update with plagiarism checking in place, unexpected speed of delivery 
Tell me, when some-one is suspect of cheating, you really not informed about that and that your rating was modified?
You all with such problems, try to understand us. We wanted this check for a long time. There is a huge need of unfair behavior detection.
edit:
There is an announcement on Facebook:
So there are again a few false positives that MOSS has thrown. We will be sending out an email to those people whose ratings have dropped with the solutions which he have found to be the same. In case you think your solutions are difference you can respond back to that email or call us and talk to us.

I like the way you betrayed your friend poke19962008… And it seems, he was punished in OCT14 and learned just one thing - to create fake account :-/

The ‘suspect’ is innocent till found ‘guilty’. I know I did all code by myself. Codechef plagiarism detector doesn’t has the right to disqualify me without even telling me about what I did wrong. And what did they matched for in all those codes was it the #include

the rating should be updated as it isn’t the problem with me, its the problem with many of us that should be considered by the admin

You shouldn’t have been penalized for that because you did solve that problem first
No. But I know one should keep the code secret or private while using ideone.
Come on just because you think some one is suspect of cheating you decrease their ratings so much… I coded every problem myself not a single help from anyone and was managed to solve 5 fully and 3 partially and all I get is a fall of 3000 pts. This is highly unfair…

I scored 650 pts in NOV14 and didn’t copy any code from anywhere, not even asked someone for any kind of help. But it doesn’t show any NOV14 submission in my account. But it still shows world rank 196 in new ranking table. This is not fair @admin. Please do something about it.
