Why brush some characters that are not in this pantomime, and brush another pantomime when you see one character? Is this normal?

This is not normal. This only shows that there are more and more unruly people. Even if there is a barrage test, it is one thing that those people did it wrong. Anyway, I think it is disrespectful to brush the characters in one cartoon in another. If you see this situation, a. Ignore and close the barrage. B. report (but when there are too many people, you can't report. I suggest closing the barrage at this time. )
