I never said that there aren't any trolls in Steemit. I said that you seldom find trolls which is not the same. What you are asking for cannot be done on a blockchain as there is no central point of control (that's what makes it censor resistent). If you could do that then it would not be a blockchain it would just a be centralized database.
