So, hey Codeforces community, as I found some cheaters in Round 1117, I'm writing this blog to expose him! (This blog is not formatted by an AI model)↵

No 1. Their handle is [user:swayam12,2026-08-30], and as you can see, he's a pupil in just 3 rounds,↵

1. Educational Codeforces Round 191 (Rated for Div. 2), Rank 5153↵
2. Codeforces Round 1109 (Div. 3), Rank 7207↵
3. Codeforces Round 1117 (Div. 2), **Rank 60**!↵

so, in his first 2 contests, he achieved a decent rank, in thousands, but in his 3rd round, as you can see his submissions:-↵
https://codeforces.me/contest/2257/submission/387410016, https://codeforces.me/contest/2257/submission/387411590, https://codeforces.me/contest/2257/submission/387414976, https://codeforces.me/contest/2257/submission/387434259, https://codeforces.me/contest/2257/submission/387436423 (1 WA), https://codeforces.me/contest/2257/submission/387438401,↵
He achieved a rank of 60, its a top-tier rank! Surpassing many some GMs, CMs, Masters! and most shockingly, in the following 2 submissions:-↵

https://codeforces.me/contest/2257/submission/387436423 (1 WA), https://codeforces.me/contest/2257/submission/387438401, **he just changed his code within 4mins, and came up with a beautiful (though cheated) approach, and wrote a very long code within this short period of time!**<br><br>↵
2. Their handle is [user:Snehasish123,2026-08-30]↵

They did participate in a few rounds before, (the very last round before Round 1117 was a Div 4 round) and here are their submissions of Round 1117:-↵

https://codeforces.me/contest/2257/submission/387404882, https://codeforces.me/contest/2257/submission/387414548, https://codeforces.me/contest/2257/submission/387419377, https://codeforces.me/contest/2257/submission/387421711, https://codeforces.me/contest/2257/submission/387457660, https://codeforces.me/contest/2257/submission/387461926 (though TLE but still counts as an attempt to cheat!)↵

**In different submissions, they are writing their code with a completely different style and they are literally submitting and getting AC on Problem A -> Problem D under just 2 mins, just with there max solving of just 800 rated problems!**<br><br>↵
3. Their handle is [user:chinoscode,2026-08-30]↵

They participated in both the rounds (Round 1117 and 1118) and here are their submissions for both the past rounds:-↵

https://codeforces.me/contest/2258/submission/388802177, https://codeforces.me/contest/2258/submission/388812658, https://codeforces.me/contest/2257/submission/387432426, https://codeforces.me/contest/2257/submission/387418987↵

They cheated so nicely that they renamed all their variable names and thought that we wouldn't know!<br><br>↵
4. Their handle is [user:harshwardhan_gh,2026-08-30]↵

They participated in Round 1117 and made these submissions:-↵

https://codeforces.me/contest/2257/submission/387403229, https://codeforces.me/contest/2257/submission/387406987, https://codeforces.me/contest/2257/submission/387411637, https://codeforces.me/contest/2257/submission/387439674, https://codeforces.me/contest/2257/submission/387447339↵

**Normally, they were just solving 2-3 problems in a Div 2 or Div 1 + 2 contest, but suddenly in Round 1117, they jumped to Expert by solving 5 problems! Was the round too easy, or were they cheating? (btw, they just solved problem C of Round 1117 in just 5 mins!)**<br><br>↵

**Ok guys, that's it for today, and [user:MikeMirzayanov,2026-08-30] and [user:KAN,2026-08-30], please check on them to prevent cheating in future rounds, and thank you for beautiful platforms like Codeforces and Polygon**
<br>
**May all cheaters don't cheat**
