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

All the codes begin with...

and then some useless algorithm templates,

and a line which is the only line that solves the problem:

exec(decompress("something I can't understand"))

finally, some useless operations on a variable.

He must tried very hard to cheat. LMAO

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 D

Spoiler

Now 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.
