Hey MikeMirzayanov, you have created an awesome platform helpful for both newbie and advanced coders. But some people are playing foul game for high ratings. I know the plagiarism detector cannot be 100% accurate but it can be improved to detect some of the "similar" codes. For example I found two users who are constantly cheating in each contest. These users are kunnu96 and ace_pocket .
So now we can close the topic as the guy has apologised. the official apology link is http://codeforces.net/blog/entry/48873?#comment-329747

I can go on but i think i have made my point. And the craziest part is how these people take out time to change code in a 2 hour contest. How to discourage the fraud is upto you. P.S. There are lot more people than these two and I will write about them too. Until then happy coding :)
Yeah they are cheating.
Yes this happens but nothing much can be done about it. But you can reduce the cheating to some extent. One thing is about people using Ideone public. Another is say no to cheating yourself. I close my Facebook tab while I am on a contest now. Many times I myself feel amazed at looking at so many submissions that pass Pretest.
But the punishment of being caught cheating should pe more severe to curb this event.
I don't think this one is the case of ideone.
Hey who are you? Have some guts to come with your true ID and then talk to me in public or in private whichever way you like. I actually don't have much time for all these dirty stuffs. I even don't care. But for you I have one thing which will help you to learn something. PS : Please have a look over it so that you don't able to continue with your easy job i.e spamming and defaming others. And please for God sake don't spam me again :(

Well, instead of calling the police or deactivating somebody's account, it might be better to stop cheating.
Can't you see that he just created fake account few hours back to write rubbish about me and I m pretty sure he is one of my batch mate who is thinking by doing such things he can demotivate me, deviate me etc etc so that I will be affected by these things as he simply feels I m better than him and would be a treat at the time of placements for him. Ask him to come in open if he can.
How do you explain your codes then ?
Could not upvote more than once :D
Well, in my justification I just want codeforces to be cheater free, is that too much i ask? And now it's your turn to provide justification of above codes... wanna say something about that?
Come to my room I will explain each and every questions I have solved but don't waste your and mine time doing these cheap things. And I don't know why you are comparing my codes with others? I know you want to demotivate me well tried man or woman. And if you are the checker then why don't you become the admin of the codeforces That's all i have to say. And please stop irritating now as I don't want next time I check my mail and would find these kinds of stuffs. User anonymouSoul sent you a message. Click http://codeforces.net/usertalk/with/anonymouSoul to view it.
It doesn't look like an explanation =)
Wait for the explanation, I'll fly thousand miles and get it from his room and then give it to you :)
Maan, aint it easier to just say sorry and stop cheating?
or it would be more easy to create a different account and start cheating again :P
Cheater detected.
Sounds like a threat
The editorials are out. Seriously bro? You should now also be able to explain the question you didn't solve :P
Hey you are not in our college and I know he is my classmate only. I want to meet him if he is writing such things why can't he even don't have guts to reveal his identity. Tomorrow like him if I will make fake accounts and wrote such blogs about you would you like it? Don't you like to meet me?
I won't threaten. I will present my case in a humble manner. I won't shout injustice and scream foul, because if there are grounds for suspicion against me, it is my duty to give an explanation, and if not, then I'll shut up.
And I challenge you to accuse me of cheating :) Good luck with that. If I don't cheat you can't accuse. Similarly, if you didn't cheat he wouldn't have accused. He collected proof and waited till he was convinced. You really don't have much of a defense here. Only thing left for you to do is present a real explanation. Otherwise, codeforces rules are clear. Your account will be terminated.
These references didn't prove anything. May be I use some templates which are prewritten that doesn't mean cheating. At last Sorry if you feel I talked you harshly and I apologize for my childish behavior and writing unnecessarily and acting towards it. Now no more comments from my side. This world is full of critics and they will continue the same because they themselves couldn't do anything. That's all.
End of Discussion
Actually the only thing different in the codes is the template , the core logic is exactly the same :P
:D :P
But who will convince him that he cheated?
We don't need to convince him. The admins of codeforces need to take action based upon evidence.
Not only the core logic,everything except for the variables looks same.
"Come to my room ?" That was quick .
wtf u asswipe writing to Mike complaining about some "spammer", but not complaining that u are a cheater >_<
Probably I should come and explain you something? Or Huyum_nik should?
That is one epic guy :D
:D
Erri Cheater
It should be Erri Cheator ( It's just a joke. Don't take it seriously )
If you are a girl or may be Punjabi dude I won't take it seriously.
Methinks he doth protest too much.
I'm just curious, why this two account name is so similar :3
Maybe they are brothers or relatives?
They have the same hometown too :P
Coincidence?? I think not!! :D
Bro there can't be coincidence in each contest between same people!!
They are cheating in usernames too :D
They really are brothers :)
I have a strong feeling that these are not different people sharing code but rather a case of a single person maintaining two ID's for vested interests. The ID's have the same surname too .
No, they are brothers. Two different people. I know their facebook ids as well :P
That explains the whole scenario then. Brothers co-operating in coding. They are mindful not to just copy paste, but slightly changing codes before submitting.
So the younger brother is the candidate master, xD
Guys, why are you voting them (cheaters) down badly?
Everyone has the right to have some fun at the first glance. :D
click here to view it pains man :p
Should I say "shameless" ?
They (cheaters) are arguing like Taylor Swift
Hey vaibhavgoyal96 and vibhorgoyal97 , say "sorry, forgive us" and take some rest.
It's just unfair for the ones that participate in contests alone, rather than in a team of 2 person
Don't you dare say something bad about Taylor! You talk bad about her -> you get downvotes, simple as that :P.
I don't know why people do these kind of things. What did they get. Fine, your rating will increase then what. Your coding skills will remain the same ( ur cheating skills may increase ). The whole community should condemn these kind of things and Mike should take strict actions against both of them.
"he can not demotivate me"dude you are demotivating all of us. The concept of rating system is to motivate a user to perform well in a contest or otherwise it would not have been the great coding community it is. And finally stop being such an arrogant fella and give explanation for the code. I don't know how you got in an IIT...did you cheated their too.MikeMirzayanov we are waiting for your response here. Please say something.
Please refrain from asking questions like "How did they get into xyz college" and stuff.
We have no right to harm the reputation of prestigious institution.
WE ARE ALMOST THERE!
bndfnmyf
We take jokers like you very seriously.
Here is the apology of the guy https://drive.google.com/file/d/0BysdF08lLW-nb1FucU83Z0dwaTQ/view?usp=sharing
