In Educational Codeforces Round 195, only 8 participants passed it during the contest.

In clist, its predicted rating is 3255, but the newcoming official rating is 2100, much lower than 3255, even lower than Problem F's 2400.

So what happened? I'm confused that this time there wasn't rainboy lol.

It's obvious that the platform hasn't raised a rolling-back for almost two months.

And more importantly, there're a bunch of cheaters in the latest contests, who should be penalized.
