Hello everyone I've seen a lot of blogs on codeforces about how to counteract AI. I don't like long blogs, so I'll try to write briefly about my vision of solving the problem.

Many people played chess on chess.com . If a person has the title of FIDE, then you can see the highlighted letters CM, FM, IM, GM, WGM, etc. But to get this title, you need not only to have a title, but also to confirm that the account belongs to you through face verification.

I suggest doing something similar to codeforces. For example, if you have at least 1600 rating and you have written at least 15 rounds, then you can apply for the following titles: EXP, CM, M, IM, GM, IGM, LGM. Perhaps we can also add specialists, but I'm not sure if this is necessary. The application will be as simple and automated as possible:

1) The system checks that you have no rejected applications for the last ~15 rounds.

2) You verify your identity (KYC) through a service that can work via API. This way, codeforces will automatically receive your Last Name and First Name. And it will add you to the blacklist if you cheat with the help of AI.

3) After confirmation, codeforces automatically puts your Last Name and First Name in the profile! This is done against people who buy verification from other people. You also get highlighted letters next to your nickname.

I believe this method is automated. And most importantly, we will get "trusted" people who can have many advantages, for example: editing gym, writing blogs (we will finally get rid of junk blogs), a separate ranking for them, perhaps separate competitions for them, as it is done on chess.com (titular Tuesday).

What do you think about it?

I would like to invite the authors to prove their solutions always. If you have written the following in your editorial, please write a strong proof:

"It is always possible" or "We can show that"1965C - Folding Strip

"The sufficiency of this condition is obvious, and the necessity is left as an exercise to the reader"1954B - Make It Ugly

"The optimal strategy will be" — I will not show an example, but it occurs without proof in many tasks.

and many more...

As a master, I can't understand simple things either. I also often saw grandmasters who did not understand and wrote in the comments to be explained to them. I have friends in real life who don't solve codeforces for this reason.

P.S: This blog is like a recommendation because this problem is very common. I understand that most authors do not do the contest for money, but this problem of editorial articles can also be eliminated :)
