Hi all,

I was struggling to solve Problem C in today's contest (Round 926) and I observed sudden rise in number of ACs for the problem C. I felt something fishy and when I just searched "Codeforces Round 926 Problem C" on youtube, I saw this video (you can send me a message if you'd like the link to report the channel) which had solution for the problem. It was uploaded when the contest was live. There are many such videos like this. The video has gained 1.5K views even before the contest ended.

To my surprise, the code in that video has the correct code for the problem (I tried submitting after the contest). This wasn't enough, The video description has a link for telegram channel, where they have shared the solution for previous contests as well.

I understand it is difficult to identify cheaters and take action. We as a community should do something about cheating in contests, for time being what we can do is report these channels on youtube and telegram. I request @MikeMirzayanov to take some action(if possible)
