I got question:

Solving tasks and saving source code should be punished and user should be marked as 'cheater' if code is used on other (but mine) account?

It sounds ridiculously.

Hi there! I’m Chubz as you can tell, but I would like to clarify some things. I have written the solutions for most of these problems over the course of the school year, because as a high school student, SPOJ is blocked for some odd reason. So because of this, I write the solutions at school. Since I’m now on break, I can start submitting them.

Ironically I’ve been trying to submit them on different days to avoid getting flagged or banned! But I would like to make my case clear.

I don’t think Rully Soelaiman (arena) cheating.
you might think badly about this account. This person is working as a lecturer in ITS. This person is
OSN counselor and learner to IMSO in computer olympic.

This is a bit off-topic but don’t know where else to go to get it noticed.

This user22 has been submitting the same solution for PIEK repeatedly during the entire night. Can’t be a judge on whether that was a bug or some monkey business, but it severely skewed the stats for the problem as well as his profile, not to mention sucking resources off the SPOJ servers. Please disqualify the duplicate solutions as they seem to have went into thousands by now.

Edit: The user above submitted the code 1500+ times during 3 days. Now there’s another one4, probably also botting as I can see 6-7 submissions being processed simultaneously, clogging the server. This needs to be sorted out.

Indonesian high schoolers probably copying a solution from one another. This has been going for a long while and seriously disturbed the score in some of the less popular problems, here they’re quite blatant:

More are submitting8 as I’m typing this.

Chances are they get problems assigned as part of their course but even if in principle they solve individually, what we’re getting in the end is a swarm of groupthink solutions distorting the scoring. I also remember some ACing using both school and private accounts, something I can’t find example of after the DPA rendered the site unsearchable.

Kacper Bąk12 wants to get a good job in IT so he shows us how to mirror Zobayer’s repository, several problems a minute. Can’t WA with this clever approach, obviously, in fact he’s the quintessential “AC in 1 go” coder, unless he presses the wrong language button when submitting. Any start-ups watching, you better run and hire this guy right now, he’ll provide a solution to any problem as long as someone else had already coded it!

There are people from Marri Lakshmi Reddy college who are making over 60-70 submissions a day and seem to be cheating from each other. Here are the usernames : @varshitha_06, @swetha37, @shivani_2001, @akanksha_varma, @sowmya_1_2. Please look into them and ban them if malpractice is found.

We have a genius who has risen through the ranks to the No. 2 spot inside a month. In five pages of submission history, there’s not a single wrong answer. Either he hides them, or doesn’t make any. Mighty suspicious, I’d say.

edit: I withdraw my ridiculous allegation!
