Recently, there has been a lot of discussion centered around cheating. While there are many people who are proactively advocating to stop cheating, some of them are cheaters themselves. One such issue cropped up today during the April Lunchtime. The person in question who also happens to be a Youtuber, running a Youtube channel named "Quarantine Engineers", with around 6.5K subs, has been proactively saying/spreading words about not cheating during contests and giving them honestly. During the contest (April Lunchtime) this guy's solutions happen to coincide with another guy’s solutions who is also from his college (NSIT, Delhi). The account on which the copied submission is made, is used by this guy to make videos/editorials after contests. Such is the audacity and hypocrisy of these people who on one hand go around criticizing people for cheating and on the other hand cheat themselves on their own account which they use to make video editorials. I am attaching the proofs as well. His Codeforces account is kassutta (Mihir Singh). The other involved person is Brother_mohit (Mohit Yadav).

I am also attaching video grab from his Youtube channel where he is using the same account.
Edit: This guy has claimed in a community post (after this blog was put up) that he has not cheated before. Whereas he is a habitual cheater. How about a few more incidents involving Not_So_Cool (bhavya rustgi, NSIT again) and kassutta for September Challenge 2020. Both have the same points as well. I feel sorry for his Youtube community, who are learning at the hands of a cheater. I'm sure if we dig deeper there will be many more incidents of cheating involving him.
I am linking two solution pairs below. As you can see, these guys have made subtle changes in their code to avoid getting detected and flagged. However, a human eye can see that both the solutions are the same. Its just that they have reorganized the codes (moving parts of code to functions, replacing a set of if statements with equivalent if statements) and are actively trying to hide the fact that they copied with each other. You can see for yourself in the links below.

While it is true that many people cheat, but this guy is running a youtube channel and has an active community of people watching him. Moreover, he cheats on the same account he uses in his video. Such incidents need to be called out publicly because the community, at the very least, deserves to know who is authentic and who is not.
