@vijju123 you didn,t told what admin decided to do on the rating change per contest for those who are recovering from 0 you only said that admin will provide +K because if +K is not enough then it will take almost half an year really to recover the old ratings
where is your +K thing? it would take almost half a year to recover the ratings. they are not even considering the performance, just randomly giving +135 to +140 rating points.
Updates as requested by the community-
- The script for +K rating is almost done. Users can expect it to be done very soon. @admin is hoping for it to be done by today or tomorrow.
- Penalties are being revised. The “Drop rating to 0” is being replaced. I can comment exact numbers only when its finished, but they are tending to keep penalties at an at least -750
- Making the process transparent is initiated. It can take some time. A rough deadline is end of this month (but may be extended if some unforeseen difficulty comes up). We’ll inform about that.
Hello all,
I am extremely delighted to inform you that as per our discussion with @admin , the concerned changes have been implemented! Please check your profile, and read about the changes Important announcement concerning rating changes following plagiarism | CodeChef .
No More Mercy will be done for any further case of 0 rating so please keep fair play in mind when you give contest next time. Also, the rule of "Change rating to 0 has been replaced by Reduce rating by X
Please give @admin your feedback at the blog. If I am needed, do tell me. Thank you for having faith and trust on your moderators. 
I was plagiarised twice. According to the rules, I should've been penalized with a deduction of 1500 rating points, but my ratings were reduced to zero.
Read point 8. Did it not satisfy the doubt?
Also, the volatility issues of users with 0 rating participating in MAY18 experienced very low rating increment. When will the rating update?
I dont think rating increment was in the plan. It was, afaik, applicable from next contest onwards.
Cook-off is due tomorrow, is the volatility issue resolved
They are experimenting and trying things.
I think you mailed me. I had a look then, and I said to mail them back. If I recall correctly, you missed the time frame. As in, the sole decision depends on @admin and I have no say there. Sorry 
@abhineet14 I see, thanks for the info.Maybe when contestant gets penalty of plagiarism the no. of contests can be made 1 again?(I know this is hoping too much; but considering it is reasonable to give me and others in similar position better rating)

This isnt a bug. Your rank must be between expected rank calculated by your overall rating, and expected rank calculated by “only cook-off rating” which led to this.
I think following what codeforces does in their plagiarism cases is the best thing. Do not consider the contest for that user and skip over all his submission.

Seems good suggestion to me. Please remind me again tomorrow, I will present it to them when @admin is online.

Yes, we are still in talks with @admin regarding this. I asked them to have a look if its a fault from their end, and if that is, then take corrective measures. I will try my best relive you guys as much as I can.
Codechef can allow this to happen twice and then if it happens third time, the user should be banned.
This will help all those people who will be caught in plagiarism due to ideone in future cases.
PS-Reminder
