Hi chromate00, MikeMirzayanov,

Please get this ID banned: https://codeforces.me/profile/longago_06

He's Ayush Ranjan from KIIT and has been CHEATING openly from a long time without getting flagged. He has given today's Div1 contest and ranked 70, reaching Master with a delta of +238.

Here are some proofs and suspicous behaviors:

• He submitted today's F1 in Div1, if you submit that same solution to F2, it will get an AC, but he didn't submit it to avoid getting an even higher rank. Here's the solution link for your reference: https://codeforces.me/contest/2201/submission/364101785

• His problem solving graphs don't match with what rating problems he's solving in contests.

• He is from India and recently changed his location to Japan, and added himself to Jiangly Fan Club.

• There was this linkedin blog posted by someone where all other proofs are mentioned: https://www.linkedin.com/posts/saurabh-kumar-84857538b_stopcheating-codeforces-activity-7414979251365445632-PWNB/?utm_source=social_share_send&utm_medium=member_desktop_web&rcm=ACoAAEPHoicB2A3sM0udELtWxNJpkzVI-igXrIg

Codeforces Lite is performing better than ever!

I still can’t believe it.

Three months ago, we had handled a total of 5000 submissions. Today, that number has crossed 150,000+!

Yesterday’s contest alone saw more than 4,000 submissions in a single day!

We’re now a community of over 3,000 competitive programmers who are regularly using the extension, and I genuinely want to thank each one of you for the incredible support :)

Codeforces Lite is helping thousands of programmers every day, if you haven’t explored it yet, you’re missing out big time. With a customizable dark theme, you get code execution directly from Codeforces, testcase verification, etc.

Let’s make Codeforces Lite the best it can be — together.

I’m excited to announce the release of Codeforces Lite Version 1.1, a major upgrade to our previous version. Previously, we provided you with a built-in code editor with templating and other awesome features.

What's New?

1) Code Execution
A built-in compilation system enables real-time code testing directly on the problem page. This is powered by Judge0.

2) Test Case Management The advanced testing framework now allows you to edit sample cases and add custom inputs, helping you validate edge cases and refine your solutions before submission. This was particularly needed for Codeforces to avoid WA on the first attempt.

3) Verdict System Instant AC/WA feedback with detailed error messages provides clear insights into your code's performance, helping you debug and fix issues faster than ever.

4) Fallback Architecture An intelligent dual API system automatically switches between Judge0 and Judge0 CE, ensuring reliable code execution even during service interruptions.
