I think users that are "not included in main ranking" should not be counted as "users solved the problem" when calculating points. If cheaters "collect AC submissions and submit them", they can easily make the points down, and I think it's not fair.

Kindly take some strict action against such cheaters,
like remove them from spoj or ban etc.

Thanks

Another problem.
Some users are hiding problems with the excuse of 'Empty Input File'.
A recent example was ANARC09E by Robert Gerbicz, username: gerrob.
EDIT: The problem is there is no problem! The problems are perfectly fine! These users are just hiding these problems, so others cannot find and solve it, reducing its point value.

Uh, why are you posting that under a cheating topic? It was hidden by a member of the editorial board because, as he said, the input file for the problem was empty. Once it is fixed it will be unhidden.

A large number of accepted solutions in short time certainly raises suspitions, but we have to be careful.

I just checked this forum to see if anyone was annoyed by my recent activities, when I resubmitted 50+ of my C++ solutions using a different compiler (g++ 4.3.2 instead of 4.0.0-8) to check if there was any improvement in performance. This kind of stream of submissions would look like cheating to almost everyone following it.

By the way, there were some improvements, but they were not consistent. I reached the first place in 5 problems, anyway. smile

EDIT: The guy has disqualified those solutions now, so I am removing the post.

Thanks for clearing that, I'm sorry for my wrong assumption. Same according Neal Zane.

carlosravl is right, one should be careful with those assumptions, and nthrgeek is also right.
On the other hand, I think, this is the place to post thus things. If a suspicion is wrong, it can be cleared easily.
