There are thousands of people cheating in contests nowadays. Difference is now a considerable amount have reached Master level performance, just see the submissions for yesterday E1!

I would like the coordinators to consider the possibility of purposefully leaking codes in these telegram groups, which are implemented in a certain long and tedious way no genuine person would. Even better if such codes passes only pretests and FSTs without making it too obvious.

Cheaters on such groups will anyways cheat. They see a code published, even if its not from their "trusted source", most would copy (especially if its a higher-up problem not leaked till now). After 1-2 such cases of clear cheating, simply ban the account.

"But they will just create more accounts" — True, yes, but at the very least, it would help the standings of the current contests.

I have been a CF contest author too, though did not implement this then, it was sad to see such telegram groups selling solutions of the problems we worked so hard for.

First half-month of Jan we had 2 rated (Div2+) contests.

2023, by the first half-month we had 5, and closed the month on 9 (Div2+) contests.

2022, by the first 2 half-month we had 4, and closed the month on 9 (Div2+) contests.

There is also a very non-Uniform Distribution within the month, (which wasnt there last year, but is there in the past few months)

December 2023 — Closed month on 7 (Div2+) contests, but in first half-month had 2.

November 2023 — Closed month on 7 (Div2+) contests, but in first half-month had 2. (3 contests in three days towards end)

October 2023 — Closed month on 6 (Div2+) contests, but in first half-month had 2.

September 2023 — Closed month on 6 (Div2+) contests, but in first half-month had 2.

Although this is not too bad, most schools and colleges have exams towards end of the month, which also clash with most CF contests. I understand and appreciate the amount of work done to schedule contests, and am not complaining. This is more than what I can ask for. Still just bringing these observations into notice of coordinators. Is there any reason for this?

I assume most students would prefer more contests in the start of the month, rather than the end.

Summer started in this part of the globe, and a bunch of virtuals over the next 3 months await me. Which would be better, educational or normal Div2s, or a mix of both? Educational are supposed to "educate" with well known ideas, but I've frequently found the Div2 qns to be better(but also more random).

Any suggestions?

Since Mike wrote the Blog, there was much debate in the comment section, which also included Mike. Since this would be setting a precedent on CF, second thoughts could have risen.

Contest got over ~5 hours ago, by this time, rating changes usually do come out...

So is the contest rated or not?
