Are Cheaters Making Rounds A piece Of Shit?

Definitely "Yes" It is not a wonderful thing when maybe 1000 cheater go for the first~ 1000th place in a rated round

Now is codeforces System caughting cheaters? For stupid cheaters the answer is yes, but for less stupid ones (who change the variables name) the answer clearly NO!

Let's we give Codeforces advices to get rid of them -_-
