822124 is solving problems during contests and sharing the solutions on YouTube. I know that after this handle will be disabled, they will likely create a new one. Please take action to ensure they cannot access Codeforces. Because of such users, many hardworking participants don't receive the ratings they deserve!
Update: I have reviewed some submissions, and many of them appear to be the same.
For Problem D: 302460567 → 302461334, 302458064, 302459851, 302458943, 302457592, 302451504
For Problem C: 302449471 → 302447393, 302450981, 302447627, 302446614
I noticed many more similar submissions, but I was too lazy to collect all of them. With users behaving like this, the contest is likely to be made unrated.
I don't know the reason why so many people downvoted this blog.
I agree with Robi_Robi(the author).
cause I am a newbie.
Why do people use YouTube videos to communicate data that consists almost entirely of text?
Easy to use, and they provide the code in the comment section.... Many text communications are available (like discord server,Telegram Group), but we can't catch them.
its more widespreadable and also the author can earn money by monitization so why not?
agreed! Needs to take action immediately.
I agree; sharing solutions during contests is unfair and ruins the competition's integrity. Codeforces should take strict action to prevent such behavior.
Good work!!
