Today, when I was browsing the Codeforces contest scoreboards with my friends, I discovered something really amazing:

1 2 3 4 5

1 2 3 4 5

I cannot understand why someone would change their default theme and code style multiple times during a competition. Perhaps this is where the gap lies between me and IGM users?

NOTE: This is just a suspicion. I have no clear evidence to prove that this user cheated.
