I am finally frustrated and have to post this .I have been observing the codechef profile of this months top contributor @laxman94 for today and have found that most of his upvotes are done by his college mates. Over the past 2 days, his classmates @harryi3t (10 upvotes), @nagendra085 (10 upvotes) and @praveen2jan (6 upvotes) have upvoted almost each and every one of his answers in a bid to increase his karma.This is just todays observation and not for the whole month!
I do not know if he is personally involved in this but i feel it is highly unethical and unfair to people like @kuruma who deserves to be Top Contributor as he has genuinely contributed and is not just getting upvotes from his friends. Please do not indulge in such activities and disturb this wonderful forum otherwise the karma system would completely lost its meaning.
