Hey MikeMirzayanov, you have created an awesome platform helpful for both newbie and advanced coders. But some people are playing foul game for high ratings. I know the plagiarism detector cannot be 100% accurate but it can be improved to detect some of the "similar" codes. For example I found two users who are constantly cheating in each contest. These users are pratyushbansal26 and bhardwaj_prakash. I can go on but i think i have made my point. And the craziest part is how these people take out time to change code in a 2 hour contest. How to discourage the fraud is upto you. P.S. There are lot more people than these two and I will write about them too. Until then happy coding :) They are keeping the main solution same only changing the template of outer code thinking that they will not be caught.. The filth and mud in their brains are making this platform dirty ,they are constantly cheating in all the prior contest .i should not be much affected by these cheaters but honest people who are working hard just to improve their ratings are disappointed after every contest because of these filthy people..

Proof- 1. CHEATING 1 pratyushbansal26 Problem link — 1520E - Arranging The Sheep Solution link — 115274425 https://codeforces.com/contest/1520/submission/115298765

bhardwaj_prakash Problem link — 1520E - Arranging The Sheep Solution link — 115290509 https://codeforces.com/contest/1520/submission/115290509

See the F solution both these guys are just changing the variable names and introducing extra variables to do the same work so that solution seems different .U can look at these codes ss attached below..

1. CHEATING 2 pratyushbansal26 Problem link — 1520F1 - Guess the K-th Zero (Easy version) Solution link — 115298765

bhardwaj_prakash Problem link — 1520F1 - Guess the K-th Zero (Easy version) Solution link — 115304856

I HAVE BEEN DOING CODING FROM LAST 2 YEARS, AND I REALLY RESPECT THE HARDWORK WHICH PEOPLE DO AND WHAT I HAVE DONE. SO, I THINK THAT THESE RATINGS ARE A KIND OF MOTIVATION FOR ME, BUT I SEE THESE TYPES OF PEOPLE COME AND AFFECT MY RATINGS THEN IT HURTS, AND I GET UPSET.

MikeMirzayanov, Aris_244_, Stepavly, Supermagzzz please take strict action against them and do justice with hardworking people.
