Today , I was just deleting some photos when I found this photo wich I took when I solved 100 problems , I was happy so I kept the photo and now I found that [user:sus] was in the top contributors on codeforces , But he had Grandmaster rate :

Now , if you go to his page , you will find that he had never been a Grandmaster rated user .

So , can anyone explain this ? // sorry for bad English
