This is a huge issue as it they are top rankers from India and there is huge price for the winners.
Please have a look at this profile: https://www.codechef.com/users/rivatus
He has got Rank 15147 is February div 2 but his rating increased to 1890?
April challenge he has rank 1417 where he did not submit any problem?
AND NOW THIS GUY IS RANK 8 in July?
Same goes on for this guy https://www.codechef.com/users/the_epitome
Have they both been plagiarizing in the contests?
Please admin take a look at this.
And someone explain me what the heck is going on here?
