CheaterKiller's blog

By CheaterKiller, history, 4 months ago, In English,

Hello Codeforces, I'm back :)

Yesterday there was Divide by Zero 2017 and Codeforces Round #399 (Div. 1 + Div. 2, combined) and also cheaters...

Let's see.

Cheaters are tejavojjala, hybrid and shivamg_isc. They are from IIIT Allahabad university, they solved same problems and their solving time is similar. I want to pass problem A and B, because they are easy problems, but I want to note that shivamg_isc copied B from tejavojjala. Names of variables are changed.

Their solution for problem C: here, here and here. Codes are same, but little things changed...

For problem E hybrid's code is different, but other's code is same (submissions : here, here and here).

UPDATE: Users chill21 and bombie are also cheaters! See their submissions for problem B, bombie's and chill21's. chill21 changed name of function recur to dfs :D How smarty. He did problem B with dfs :D. And bombie wrote // Never Underestimate Yourself // on top of code, by cheating you are underestimating yourself...

Good luck and contests :) Don't cheat!

Sorry for poor English.

Actually you are cheating while reporting cheaters. Sure, it is not the same way of cheating and it affects nobody but still having multiple accounts is against the rules, I believe. Why not report them from your main account? Also, you may greatly increase your contribution this way.

    I think having multiple accounts is not against the rules, participating in contest with multiple accounts is against the rules.

    In time of they cheated, there was not CheaterKiller in Codeforces :D . Also no one said that they are not cheating.

    AIM TECH Round 3 (2016-08-24).

    Also I think you are one of cheaters (tejavojjala, hybrid or shivamg_isc) beacuse there is "iit" in your nickname and your account created 20 minutes ago...

But you are not able to give cheaters punishment... It takes lots of effort for the sake of completely fair contest result.

    Do the cheaters get banned or something (sorry, i'm quite uninformed on this matter)?

      If you click into the profile of the cheaters mentioned in the blog, you can see they are still taking contest recently. So I would say the answer is no.

Am I the only one who enters your blogs only to see if my nick is there?

It's like leaving a shop and going through electronic gates that detect stolen products. I know I did nothing wrong but I'm anyway a bit afraid an alarm will turn on.

Is it a cheating like a love triangle or non-degenerate triangle?

    No , it's not. He reports these kind of cheating cases by matching the codes not nationality.Read his previous blogs you will get your answer.

I am sick of seeing this blog in recent actions all the time. Write to the admins and MikeMirzayanov if you want them banned.

      Not really. This blog keeps sinking to the bottom of recent activities, and then someone comments and deletes, putting it back on top. I'm guessing this is done to draw admin's attention to the blog. I've noticed this happen for many days. So today, when I-don't-know-who commented+deleted something, making it appear back on top, I thought I'd give them the revolutionary idea of writing to the admins.

      BTW you brought it to the top as well
