Title: Cheating Report: Account nvhoang in AtCoder Beginner Contest 479
Hello everyone, Note: Since my English is not very good, this blog post was translated and polished with the help of AI.)
Following up on my previous post regarding account nvhoang (NGUYENVUHOANG), he has once again exhibited clear signs of cheating in AtCoder Beginner Contest 479 — in fact, I am completely certain of it. After several cheaters were removed from the official standings, his rank jumped straight into the Top 5.
To verify my suspicions, I prompted Claude (Sonnet 3.5) to solve problems F and G. To my surprise, the core logic, algorithmic approach, and code structure generated by the AI were almost identical to his submitted solutions, with only minor tweaks made to disguise the AI footprint.
Anyone can easily verify this by generating a solution using Claude/ChatGPT for problems F and G and comparing the output directly against his submissions here
Furthermore, it appears he has become aware of anti-cheat detection: he seems to deliberately stall and delay his submissions to avoid triggering automated flags for suspiciously fast solve times.
I urge the AtCoder admins and community to inspect his submission history for ABC 479 and take necessary action.
atcoder_official read this please.

dirty cheater aren't we...
mambo
Ahanab bro is down so bad even mambo called him racist... [:wilted_rose:]
bro you clearly a cheater, it's so obvious all you need is search in https://cf-cheater-database.vercel.app this must be some 10th account, stop looking at random things, and commenting useless things everywhere, unless there is reason to do so, because all you do is bring your cheater shit in every comment section
see my submission before yapping mf.
btw here are your accounts, fractal73 attractors AttractorsTheory open90 SwastikPandey_cheater i wonder why 3 of them are banned, 4 including fresh_tangerines
and lets not forget that when id fresh_tangerines became pupil, then u asked for its password to bricked_ and then you cheated on this id for next 4 rounds to get your main account a bit of more rating.
while my accnts are swarya i didnt knew rules so i cheated then i did most fucking dumb thing which was defending, after that i left it and created fresh_tangerines here i did that on 1 ques then gave it to bricked_ who u manipulated to get accnt to cheat a bit more., since then or u can say since 1.5 years im doing a fresh start unlike u.
bro, what is this even, like where is the cheated code, and wtf these 10 account, idk how is that even related to what I said, and what are you trying to say here and to who? Really who are you trying to show and what are you trying to show? Lol, you don't have any proof that I cheated, you just accusing me because you are angry that you are cheater and I am not
oh my god , your 2nd account attractorstheory is marked as cheater on cf-cheater-db
show cheated submission and show the connection between account, ig you just trying to make some assumptions just because you angry that you are cheater, if you need proof that you are cheater then I have proof
swastik_P lol, first of all no, unofficial websites are not proof, because anyone can make website and mark as cheater, the reason why I said this, is because I have proof like check your second comment on your account, also I see you funny decided to make a blog, sure I can't make more then 4 comments in 60 minutes, but if you want spread misinformation and lies, then sure go ahead, I'm not replying to that
cf-cheater-database isnt it enough.
open90
EDIT: uhh second comment? it was perfectly fine ig whats wrong in it??
There's levels to being racist son
