Well, Well, Well -- was I wrong to accuse AK_YZY of cheating. I first posted a blog about this guy when he was a pupil, and now look at how high rated he is. But I was right, finally, his submissions to DeepInfra round 1 were all skipped: https://codeforces.me/submissions/AK_YZY.

But unfortunately, his rating was not rolled back nor was his account banned. I can't wait for this cheater to get deleted off of this platform.
