Today I've found that user "suby" did the same thing as posted above. He has been rank #2 at SPOJ for a very long time.
Here are some interesting code:
Problem ANALYSER. submission id 1326682:
This code looks pretty nice, but when I pull the scroll bar to the right:
The same things can be found in these submissions too:
Problem RP. id: 1344111
Problem LARGE. id: 1602571
Problem BACKUP. id: 930772
These are not only things he even does. After submitting cheating program and has been rejected by my own test cases on problem BACKUP, he submits my classmate g201513's program. At that time, the password of my classmates' account @ SPOJ only has 6 digits and is easy to decrypt by brute-force. Maybe this is the reason why suby gets almost all g201513's program @ SPOJ.
See these submissions on my problems:
Problem Code submission id Original Author submission id
BACKUP 1260794 g201513 855371

PROFIT 1207304 g201513 1207070
SEQ2 1325178 g201513 836309
Only to my hard problems, he submitted so many cheating programs, one can image that many of his submissions is cheating ones.
Obviously, suby can not finish these problems himself. These actions are cheeky.
By the way, user ---(login: neophd) has been banned a long time ago. But his name is still shown on the ranklist. So would the admins please kick out these two persons from the ranklist? Thanks.
