This guy is the admin of Zhejiang University Online Judge, so he has lots of programs to submit 
He has done the same thing @ PKU Online Judge long time ago.

hi.My account in SPOJ is aiolios. And there're some same problems between
VOJ(vn.spoj.pl) and SPOJ(spoj.pl) . And i submited my code from VOJ.
You can find here
vn.spoj.pl/users/canhteo
spoj.pl/users/aiolios
all of them are mine.
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.

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.

i think both accounts are of the same person, today from one account he added a problem in classical section and then solved it immediately, 
,
please admins check it, and if found true, then take the appropriate action...

Please have a look at this user :
spoj.pl/users/abhipr1/2
He has solved all problems of GNY07* and SAMER08* but has failed to solve simple problems like CPRIME, ANARC09B, CANTON, CHOCOLA, MKBUDGET (its a DP problem of the simplest kind and yet he has solved SAMER08C and SAMER08D). Even the submission times don't differ by much. I might be wrong here but still looks suspicious.
This user submitted 9 different problems within two minutes.
Pretty strange!
spoj.pl/status/smoochy/2
Edit: Furthermore: 19 different Problems in about one hour. Seems like he has copied that.
I highly doubt that user is cheating. Submitting that number of correct solutions in such a short time means it is more like they aren't cheating; they're probably submitting their own solutions from another online judge. The problems aren't related in any way, so there is no way they would have downloaded solutions for those problems from one place.

User mohamed_maher1 is problemsetter of problem 8315 and 8351 (problemcode: MIDO!) and was(!) problemsetter of 8349 and 8319 (for the last two problems the name of the problemsetter changed some hours/minutes ago).
User mido22 has AC submissions to these problems, especially he actually has top rank in challenging problem 8315. Short time after I wrote a comment below problem 8315 where I pointed out that this user "mido22", who called himself mohamed_maher is obviously problemsetter and has successful submission for these problems, the following happened:
- user mido22 with former name mohamed_maher changed his name to "mido22"
- my comment below problem 8315 was deleted
- my AC Python submission for 8315 that was somewhat shorter than the 340 Bytes solution of mido22 was disqualified by problemsetter
- problem now is no longer opened for all languages but restricted to some languages
I don't know if someone is cheating here, but user mido / mohamed_maher should explain these things.
Moderators please have a look at https://www.spoj.pl/problems/NUMWORD/2.
What happens there has a bad taste.
Actual top rank mido22 belongs to the group of problemsetters or is related to them.
Either he is a genius in shortening C++ code (which is not very likely if you look at his results in other shortening problems, e.g.
https://www.spoj.pl/problems/WORDNUM/ or https://www.spoj.pl/problems/NPRIME/) or he only prints the expected output.
See also problems 8351, 8373 and 8374 from same group of problemsetters: For all those problems user mido22 submitted the first AC solution short time after the problem was published.
I agree with numerix and think that problem-setter shouldn't submit a code for his tasks (unless he's not suspiciuos) after anybody submitted a solution in certain language. In other words, psetter should write the shortest program he can for his task and exactly after adding the task he should submit the solution.
When somebody wrote shorter code psetter should be out of competition, in my opinion.
(the idea doesn't concern SHORTEN)
It's not just submitting I guess. You are doing the same with SHORTEN with separate account, aren't you? And that's OK, kind of shows what is possible (where it makes sense of course).
From numerix's posts I conclude the main issue is changing rules after publishing based on god-knows-what (why no python now?) and suspicion that problem-setter's solution(s) isn't "generic", designed just for known tests.
I do as well agree with numerix. Achieving a top position in the ranking is cool but like this it is kind of smelly.
hi all,
i'm really one of the problem setters for the account ( mohamed_maher ) but it real i don't add problems except "EGYPIZZA"
i don't want to call me a cheater i can cheat with many codes without solving them but u can ask leppy when i have problem in doing my code i put it in the forum
i don't cheat any code and my real account is mido22 if it is not permit to be one of the problem setters of kawmia institutes problem setters , anyone of the admins can remove this account but it is not for me only as i said before .
i told numirex before that fact but i think he didn't believe me.......
i want to know the other user comments and any one can see my account , i am 370 not from first 100 because i don't cheat in codes and i 'm very sad to be put with cheaters plz all understand me and i want to know what can i do for all users that think i'm a cheater
when some users said that i am in the top rank of some problems that is because when one of my friends in kawmia institutes PS want to add problem he told all of us to add it and i solved them before they put it then i submit my code
