I have discovered two submissions from users with very similar usernames and nearly identical code: https://codeforces.me/contest/2209/submission/367657320 and https://codeforces.me/contest/2209/submission/367660965. Since using multiple accounts in rated rounds is against Codeforces rules, I request that you investigate this case.

After so much time, I finally reached 1900 (at last). Although I now have 1900, I didn't experience any real sense of inner satisfaction—after all, I didn't make it to the final stage of the All-Russian Olympiad. By the way, here's a strange tip for those competing on Codeforces: don't try to come up with something complex on ABC problems—more often than not, the problem is easier than you think. Good luck to everyone and bon appétit!

The number of people cheating during rounds has increased recently, so why not start using measures that have long been used in some online Olympiads, namely, invisible texts with mod output. Moreover, due to the nature of the testing, the person will only realize they've been caught when the non-pretest testing begins.

Recently saw how some users (I do not know exactly who) use Codeforces accounts embedded in the Internet for bots and try to slow down the testing system (I did not participate in this and could not prevent). We have previously encountered that Codeforces warns users about the loss of their password, or an unreliable password, so why not do this: if the account is in the merged database, a notification is sent to the mail and the password is regenerated by the system. This method will reduce the abuse of the merged account on our favorite platform.

I recently started thinking about changing my codeforces handle. One of my cool nicknames belongs to a blocked account (this account has nothing to do with me). Is there a way to contact support or otherwise free up the handle so I can switch to it in the future during the New Year? Thanks in advance for any advice.

As I wrote in my previous post, I would like to participate more in the life of Codeforces, so if you need a tester for a round, I would be happy to join your round :)

(At the time of writing this post I have 1542, Carrot shows +77 so I'll write in advance) After so much time I've reached 1600 and would like to share a couple of tips: if you want to specifically increase your rating, then understand what you're better at — coming up with constructive solutions or writing complex algorithms. If it's the former, then it's better to participate in lower divs, since divs 1-2 have many different algorithms, but this method only works up to 1600, beyond that you can't do without algorithms.

I would also like to ask for advice on creating problems and uploading them to polygon (since I want to start teaching and this skill is very necessary). At the moment I'm thinking of starting to grind more algorithms and reaching 1900, I would be happy to help with preparing or testing rounds.

thank you all for your attention and Mike for the wonderful codeforces

UPD: how do people find this post?

UPD2: YESS NOW OFFICIALLY 1600
