humblecoder disqualified himself these submissions.

Before: Current world rank: #146 (64.1 points)
He still has problems of University of Ulm Contest and Kurukshetra ( not so surprisingly the entire sets 
)
I think only the setter of that problem, can verify this. But i'm quite sure he has used judge solutions.
Cheats are so bad. 
I am the problem setter of KOPC09. His submissions for problems RAINBOW, KGSS, PROOT are judge solutions.(I saw only these problems in his profile)
EDIT: Now he has disqualified his submissions for Ulm contest and KOPC problems.
Hello,I doubt that this guy is cheating spoj.pl/users/macedonian_boy/2
what makes me dubious when I notice that this guy is submitting solution too fast which is virtually impossible for any coder to solve in that time gap. Take a look at this : spoj.pl/status/macedonian_boy/signedlist/4
I request the concerning problem setter/administrator to look into his solutions and take appropriate action if found guilty.
You're right and I know, what he is doing: He found out where he can get amaroq's solutions from the web and now he is submitting them one after another ... 
Hello numerix,yes you are right,just see his rank now #30 .
I like to request the administrator attention,It's not worthy to allow a cheat to hold such a rank.
Yes, I noticed that. This donkey is submitting my solutions in rapid succession. I guess that is the consequence of my putting them on my website. I loath him and I pity him, but I see no reason to remove my solutions from my site. I've added a short motivation though and hope others will not follow his immoral example. But I'm probably too optimistic.
To be honest, I'm not really surprised.. if you don't want your solutions copied, don't make them publicly available. If you want to make them publicly available, you should expect a large number of people to copy them, that's just how it works.
No, it isn't a surprise at all. It's more surprising that it does not happen more often.
@amaroq: Yes, I think you are too optimistic ...
Or maybe too naive.
I like to believe in the goodness of people and, aside from one or two black sheep like that Macedonian, most programmers solve problems for the same reason I do, because they love to solve problems. Copy/pasting other's code takes the fun out of it.
Yes, it is too naive. I'll consider my options.
Yes there is no point for removing your solution,most of the classical problems solution are available in the web.A person good with search engine can easily find them.Your solution just increment the counter.
A person submitting others solution with just copy paste gets nothing but wasting his own time.
Out of interest, why do you put your code online? The only result I can think of is people copying your code; it's not like reading someone elses solutions tends to help inexperiences programmers learn anything (quite the opposite actually, at least from what I've seen; the true learning occurs in coming up with all the ways that don't work, and debugging). I haven't actually seen your site myself, so I'm probably missing something, but I was wondering..
Why? I don't know, really. Why do people create websites or write blogs?
The banal answer is that I wanted to create a website and I had nothing better to put on it. I had a vague idea to write something about programming, which is my passion, but for the lack of contents I started to solve SPOJ problems to find inspiration. It got a little out of hand: I spent lots of time solving problems and so I started to put the solutions on my site. Nothing else, really.
I don't know about the educational value of reading other peoples' code. You're probably right; you seem to be more experienced in that matter. Often the best you can learn from it is how NOT to program. But I never had an audience in mind when I put them on my site.
As I said: I'll consider my options. I will probably dump the whole site eventually anyway.
I know your site and if I remember right, there were not only the solutions, but a short hint (one or few words) on the basic idea to solve the problem. As I am really unexperienced in algorithms (I never had any lessons, didn't study that kind of thing, never participated in any contest), that simple hint (e.g. not more than "DP") helped me on the one or other problem to look into the right direction.
Perhaps that could be a way of connecting SPOJ and personal website: No solutions, only hints.
I know the link, but i like it since it has classification of problems which is a good thing, but not source code.
Maybe you can do this, keep the page (without source code) if anybody needs source code, he can email you.
I think that's good. I dont see any point for posting code especially when we have really helpful people in the forums.
Thanks.
The author disconnected the solution ... So No more cheating possible from that source ... but what about the cheater ?

He is still in the global ranking system !?
