1. What does it mean?
분탕 describes deliberately creating trouble, often by starting quarrels or pushing inflammatory claims in a group. It can name the behavior or, dismissively, the person doing it.
Also written or said as buntang
2. The nuance
It is a negative accusation. A genuine question or criticism is not automatically 분탕 just because regular members dislike it; the intent and behavior need separate consideration.
3. Examples
“서로 싸우게 만드는 댓글은 분탕 같아서 반응하지 않았어.”
The comment seemed meant to start a fight, so I didn't react.
“규칙을 묻는 새 회원을 분탕으로 몰지는 말자.”
Let's not treat a new member asking about the rules as a troublemaker.
