"assassin"'s submissions are interesting, it's the pseudo of the login revenge13 : (141 problems solved in his first month on spoj)
The login/pseudo system is not perfect to track those young killers but the login/pseudo match appears on the "TOP Coders of last week" list in the spoj homepage. So:
Admin look into this:
(in particular AMSCO1, AMSCO2 which is the reverse problem totally different of AMSCO1)
Shame on Francky who banned me when I was in hospital in December 2014 cause I was ranked better than him in French's rankings !
Now my health is better and I can react:
I was active on spoj since the beginning of 2012 with more than 10000 submissions including a lot of WA/TLE. I lost all my work even
the number of AC solutions(probably around 200 or 300). My AC problems were not on the internet. As problemsetter I published 3 problems: AMSCO1, AMSCO2, FMORSE1 Before I was banned, AC solutions for 2 of those problems were published on a blog, but I don't see cheating solutions in the AC sources before I was banned. My 3 problems are still available on spoj after the banned action.
As I have said killers actions are really boring for the SPOJ project as I think the Admin can't verify everytime the reality of those accusations of cheating (sometimes the problemsetter can).
I think the hard problem's constraints problemsetter reputation of Francky shouldn't have been sufficent to bann me. He is also well known to trap problems to tutorial quickly and sometimes abusive, and well known also to put harder constraints to problems to monopolyze the problem's source answers to have the tricks of the solutions of others (as when he becames the problemsetter of the hardest constraints problem he can see your sources)
