CheaterExposer's blog

By CheaterExposer, history, 9 months ago, In English

I was looking at the standings of CodeTON Round 6 (Div. 1 + Div. 2, Rated, Prizes!), and I noticed this person submitted problems in reverse order and very fast, which made me very suspicious.

I investigated more and found out that he had one more account that also participated in the contest.

It was obvious they were the accounts of the same person because they had similar names and organizations and used exactly the same template in the past.

Then I started looking at the codes.

It was obvious that the codes submitted by TimaDegt were changed versions of the codes submitted by TimDee. He wanted to escape the plagiarism detector, and he was successful because his account didn't get skipped. However, the similarities are obvious. The codes of TimaDegt use the same defines and coding habits, like whitespaces and newlines.

However, this isn't a good enough proof. If it weren't for a mistake he made, he would've gotten away with it.

He submitted exactly the same code from both accounts, which proves he used both accounts in the contest.

I looked at other contests and found many more contests where he also used both accounts. They're also full of many "coincidences".

People wouldn't expect a high-rated person to cheat, but he did. He's also a medalist from IOI 2023 (Timur Degteari), which only makes things worse. I hope the 2 TON he earned from cheating was worth ruining his reputation. I also hope that Codeforces gets better at cheater detection.

I also hope that Codeforces gets better at cheater detection.

Actually, checking not only AC solutions, but also skipped solutions with passed pretests would have helped to catch him.

    I agree. Codeforces should check every submission. That would have helped to catch him.

It would be kinda funny if he gets dumped for breaking cf rules.

Codeforces don't do plag checks nowadays, you can check for last few contests. Even for the contests which they have done plag they have not changed ratings and leaderboard accordingly. MikeMirzayanov when will be having plag tests, so that cheating again can be controlled. This only motivates others to cheat.

    If you're so good, why don't you write the code yourself and give it to Mike? I saw tens of those 'WhY iS pLaG tEsTs sO tRaSH, cHeAtErS eaSiLY gOt AwaY' comments every time I read the blog section. Plag checks aren't good enough doesn't mean that Mike didn't do a thing. Honestly, I'm tired of those comments. It's dumb.

      At least read whatever I have written. Being an IM at least I can expect this much from you. I'm not criticizing the quality of plagiarism tests, but rather pointing out that these tests haven't been conducted, and the ratings haven't been adjusted accordingly.
      It's dumb to comment/reply without reading the comment

        Go to the contest section, check skipped submissions and see it yourself :) Mike did plag tests but no plag test can catch all cheaters. Easy reasoning. Maybe next time I had to write a MO-styled proof or something before speaking to you.

I don't agree with you CheaterExposer. It's hard to gain money nowadays.

Earning 2 TON nowadays is like trying to find a unicorn wearing sunglasses, playing the accordion, on a unicycle, while juggling flaming tennis balls.

It's rarer than a four-leaf clover in a field of three-leaf clovers.

It's more elusive than that sock that always disappears in the laundry.

It's scarcer than Wi-Fi in the middle of the Sahara Desert.

It's harder to come by than a polite YouTube comment.

It's as difficult as finding Waldo in a crowd of one billion Wallys.

In conclusion, earning 2 TON today is basically like winning the lottery, except the prize is just enough to buy a fancy coffee and a donut.

                  My graph looks like a frying pan for approx 1 year. So no worries about your current pancake graph anyway, you'll probably get there someday.

                  Oh wait you are half a year in CP, then that explains it, that's pretty normal or already good ig

    That's why he should be banned from IOI to prevent alt accounting to get extra medal.

    It is fine as long as he doesn't get a medal on more than 1. Because more participants at IOI => More medals at IOI.

It's been almost 3 weeks without any action against this cheater. It makes me sick to see people cheat without getting any consequences.

It's also bad for Codeforces since now it seems like you can get away with cheating if you're high-rated. I think everyone should get fair and equal treatment.

    I agree. TimDee is the 2nd submitter of that same code, which means it should get banned.

    Honestly, I'm really surprised how he didn't get any punishment yet. This isn't his first offense, he escaped plagiarism detector many times.
