He is a big big cheater who tries to get away from plagiarism by converting code to python . After his main account 1_2_3_4_5_9 got caught he stopped giving contest from that account and started with 10_11_12. He has now reached Candidate Master in both of his accounts . He has another account by the username 14_15_16.

I am writing this to just report some cheaters I found in the latest round (#804). aman_cod, bored_kid, amber_100, 1_2_3_4_5_9 are the ones that have cheated.
Have a look at the submissions of problem E from the contest Please look at the code in main void and compare as they have obscured their code to avoid plagiarism detection..
First one to submit : 162806135 Then the second guy submits it in python : 162804059 Then these two submitted the first code as it is but with alot of unnecessary code : 162802356, 162804537
To confirm you could also match their other submission from the contest and will find the similar pattern described above and all four of them solved the 4 questions i.e., [A,B,C,E].
Please MikeMirzayanov and geranazavr555 look into it and ban these guys.
Sorry for posting a blog which does not contribute anything to the community.
He had made a telegram channel containing 5600+ members on which he publish free code on that channel, the last contest Div2, D's solution was made by him say that yesterday, He also help other people to cheat in Online Assessment of all the companies with online test. He have a team size of 7-8 people who help for this.
Abhipsita Das is the leader of this (his linkedin)... this is a student of IITBHU B.Tech+M.Tech Dual Degree Metallurgical Engineering, he even worked at Scale AI, he must have got that offer with the title of master. The funny part is he have also mention this on his linkedin that He is master on codeforces.
In these Images I have not shown any channel name or participant name so that I dont promote them, this below is the list of member of that telegram channel
