In today's contest, as I was searching for solutions, I stumbled upon this unique standings page. It is flooded with accounts bearing anime character names. Upon checking, I noticed that all these accounts share the same creation date, along with identical solutions and submissions, with slight variations. Note: unmark show unofficial
Too many normie anime.

All of them passed task A,B,C,D without any penalty.
I also noticed that they all participated in the same contests. Like "Goodbye 2023".
They have the same graph, spot the difference lol
I guess I would be getting more +ve delta hehe after plag check
Yeah, for sure. There are about 39 accounts, and even an accounts we can't see, but the plagiarism check may detect it.
Whom should we mention to alert them about this mass cheating?
mentioned mike already

I already reported 3 weeks ago but Mike didn't do anything about it :(
and then some useless algorithm templates,
and a line which is the only line that solves the problem:
finally, some useless operations on a variable.
He must tried very hard to cheat. LMAO
What a amazing cheat way that all the "useless templates" are different lol
This let me think a way of having high rating:
Create a base account and a lot of accounts. Use the base account to solve the problems normally. If you feel good, choose some accounts to submit the compressed solutions.
There should be a rule against obfuscating code
Only cowards use alt accounts
As an alt, I don't agree.
Understandable. Cowards doesn’t agree!
Looks like a cheater is trying really hard to not get caught and he succeeded this time....
it's not only this time, he participated in 4 to 6 previous contests and he passed
But as this post is sent, I think he (or they?) will be caught soon.
Maybe @omeganot and @sum (two authors) will be useful.
No clue, maybe mentioning mike will do MikeMirzayanov
unfortunately i dont think authors are able to do anything about this. I think only Mike or admins can remove these cheaters :/
CPers and their connection with anime is very deep
About 70 down votes, dude is abusing his alt accounts lol
what's the point of even putting in that much effort just for an ego boost?
maybe he sells boosted accounts?
Seriously, will this case just be passed over? There are 39 bots taking rank sub 500. Anyone can see these are obviously bot accounts by their submission time, account creation date, and code. Since they are so many, even now it affects the scoreboard and I wonder how many bot accounts I'll have to fight if these kinds of cases just get passed over.
Probably it will not pass, i can't remember when was the last time they made a roll back, but i expect a roll back that clears the leaderboard tonight or after the edu tomorrow, just be patient.
It's very easy to find who the culprit is, actually. By taking what is inside the exec function in their codes (the
decompress("a bunch of bullshit")
thing), we get the source code that got processed by some sort of program and mass submitted in the bot accounts. For example, here's the source code for DNow we just gotta have a program search for this on the contest submissions and find the author of the code.
MikeMirzayanov, rating had rolled back recently, however, these accounts aren't banned yet. Please do something.
MikeMirzayanov, are you there?
