Hey MikeMirzayanov, KAN this user cs_tree skips his solution, whenever there is a chance of huge decrement in his rating. This is the second time I've seen him do this.
Screenshot during the contest : 
Screenshot after the system testing was completed : 
He submits the solution in C++ whenever he wants to get his solution skipped.
Here is a screenshot of his previous skipped contest. 
This kind of behavior is unacceptable. Please look into this matter and take strict actions against this kind of people. It is very disheartening for people who give contests regularly and go through the ups and downs in their rating.
I had also commented on a post but there was no response from the community : link
Some links to other blogs on this matter of cheating :
The point of the blog is that some serious action has to be taken against them. If you just make them skip the contest, that's not fair. Even more people would try to do the same. This is against the community standards.
Though I don't like Codechef, but one good thing about them is that they reduce the rating of the user when they are caught in the case of cheating.
P.S.-> They don't have a good plagiarism checker XD
Feel free to give your suggestions about what should be done to these people.
