If swearing is spraying, what is the name of the person who scolds spraying?

I think you have misunderstood the word spray. I believe what you mean by spray is the kind of person who often causes trouble to others online, often without thinking, out of thin air, or for the benefit, his subjective consciousness is particularly heavy, regardless of morality, logic and facts. Swearing is a behavioral feature of spray, which belongs to common things. And people who scold spray are generally vilified for no reason, or return to spray with logical analysis from a rational point of view for the truth of the matter. This is not to scold spray for no reason. Just as others violate you for no reason and call it justice, it is normal to fight back against him. Therefore, the person who scolds the sprayer may be just an ordinary victim or a defender of moral justice.
